The SI system is based on six primary units as follows:
Basic SI units
Quantity Unit Symbol
Length Metre m
Mass Kilogramme kg
Time Second s
Electric current Ampere A
Temperature Kelvin K
Luminous Intensity Candela cd
In addition to these there are a number of supplementary and derived units. We give below a selection of those which are most likely to be required by students using this book. A full list of the SI Units and conventions is given in BSI publication PD 5686.

The SI system of units and conventions
The initials SI are an abbreviation for Systeme International d'Unites (International System of Units), the modern form of the metric system, finally agreed upon at an international conference in 1960. It is now being adopted widely throughout the world and is likely to become the primary world system for units and measurement. As we shall discuss below, the system rationalises the main metric units of measurement and standardises their names and symbolic representation. It also rationalises certain mechanical principles and conventions.
The British system of weights and measures is many centuries old, and the derivation of its units with their multiples and sub-divisions is often obscure. The system has been refurbished from time to time but the yard and the pound with their multiples (e.g. mile) and sub-divisions (e.g. ounce) have persisted; so have such ridiculous measures as 5+ yards = 1 rod, pole or perch, 4 roods = 1 acre or 141b = 1 stone remained with us to try the mental agility of generations of students, not to mention the more mature, and less mentally agile population.
The metric system was founded during the French Revolution and has been adopted for use by most countries with the notable exceptions ofthe British Commonwealth and the U.SA., but even in these countries it is used for precise scientific measurements.
The basic units of the SI metri,c system are the metre and the ki10gramme and it is exclusively decimal, so that all multiples and subdivisions of the standard are found by applying factors of 10 (1 kilometre = 1000 metres; 1 ki10gramme = 1000 grammes; 1 hectare (area) = 100 X 100 square metres, and so on). In the English system, of course, there is no such orderly pattern and indeed, the foreigner might well question our sanity when he hears us refer to 112 pounds as a hundredweight.
However, we have, at last, been caught up with the progress of the times and as a nation we have decided to change over to the metric system. The entire text of this book conforms with the SI system and the object ofthis introductory chapter is to provide help and reference for the reader as he finds his way into what may seem, at first, to be a complexity. The best advice that can be given for achieving rapid progress in coping with the change is to become familiar with the new measures and to learn, as soon as possible to think in terms of them, and not to persist in making mental conversions back to the old units. This process can be speeded up by acquiring, as soon as possible, a mental appreciation ofa range oflengths, weights, capacities, etc. Some of these could be (say) the mental judgement of 25 millimetres, 1 metre, the weight of 1 kilogramme, the amount of fluid comprising 1 litre (1000 cm3) and the pressure corresponding to 1 bar (approx 1 atmosphere)*. In this way it will soon be possible to think of these measures in their own right and not grope around converting them to their English equivalents (1 kg = 2.21b and so on). A similar process is concerned in the learning of a foreign language where fluency will never be achieved until a student thinks in terms of the language concerned and abandons all attempts to interpret mentally from, and into, English. It is well known that another language is quickest learned by living amongst those who speak nothing else.lfthe reader can approach this new mathematical and scientific language in this frame of mind he will find that the former system will rapidly recede, so increasing the ease with which he can cope with the problems involved.

Jeep Tops: Anatomy of a Jeep top
Jeep tops are fairly universal Jeep accessories in that everyone from casual Jeep owners to hardcore off road enthusiasts has some basic knowledge of what they’re about.
But Jeep tops can get more complicated that one might think, and while it’s hard to go wrong when making a purchase, having an intimate knowledge about them can go a long way in extending the benefits.
For this reason, we’ve dissected nearly every imaginable Jeep top to take an in-depth look at what makes them must-have Jeep accessories.
Which Jeep Top?
It’s an age old question; perhaps one that has been asked since the time of the dinosaurs. Not really, but choosing a Jeep top has always been a decision that requires a fair amount of thought.
At first glance, choosing a top seems pretty simple. The features are all plainly stated, pictures give you an idea of what to expect looks-wise, and your particular environmental situation further dictates which one you need.
But there are also many factors that aren’t taken into account when shopping for a Jeep top. Intangibles like installation and frame style are examples of lesser-known aspects, while things like road noise or insulation are factors that can only be experienced firsthand.
With this in mind, I’ll do my best to cover aspects that are typically unaccounted for.
Factory versus Aftermarket Jeep Tops
When it really comes down to it, there isn’t a huge discrepancy between what both factory and aftermarket tops have to offer.
A factory Jeep top will give you that genuine Jeep look and feel, plus the added security of sticking to true Jeep accessories that follow the same standard of quality as the vehicle itself. Aftermarket tops are for the most part similar to factory units, but with a few exceptions.
Although both versions of Jeep tops are made from the same materials, equivalent quality, and with the same purpose in mind, aftermarket tops offer certain features, benefits, or other Jeep accessories that you might not get out of factory units.
For instance, certain aftermarket tops have been optimized to reduce road noise better than a factory one. Also, in the event that your Jeep top needs replacing, aftermarket replacement options are typically cheaper than factory tops. For these reasons, aftermarket options usually make for favorable Jeep accessories when replacing aging factory tops.
Narrowing It Down
The first and most obvious way to categorize Jeep tops in terms of need is by splitting up hardtops and soft tops. Clearly, the two styles are distinctive enough that each one serves its purpose in different ways.
Jeep Hardtops
Hard-style Jeep tops are a never-fail option. They rarely if ever need replacing and provide enhancement and heavy duty protection. In addition, they offer a number of handy Jeep accessories, like power windows, a rear window defroster, and more. Hardtops come in a one-piece model, or a two-piece configuration with a removable sunroof.
On the flipside, Jeep hardtops are not easily removed and stored for those who enjoy open-air summertime driving. Hardtop hoists and storage-based Jeep accessories are available, but require added purchases.
Jeep Soft Tops
For those who love customizability with their Jeep accessories, soft tops are the way to go. Available in a variety of designs, Jeep soft tops offer the kind of versatility, comfort, and style that justify a Jeep purchase in the first place. Plus soft tops are easy to install, remove, or store.
On the other hand, soft Jeep tops aren’t exactly ideal for colder weather. Their thinner material and fabric construction leaves them with poor insulation, and also gives them an average lifespan of only 3 to 5 years before requiring replacement.

Jeep Hardtops
When it comes to hardtops, making a choice and meeting the requirements for installation is relatively easy, and getting the right Jeep top is usually a simple matter of picking either a one or two-piece top.
Two-Piece Hardtops
The two-piece hardtop is the definitive Jeep top for year-round performance in any climate.
On one hand, you get the protection and insulation of a full-fledged hardtop during the winter. Then for warmer weather conditions, the cockpit features a removable roof piece for open-air driving.
In addition, hardtop Jeep tops come with a vast assortment of unique features and Jeep accessories like a fiberglass-reinforced plastic composition for durability, an in-mold gel coating for fade resistance, rear window vents, a rear window defroster, tinted tempered glass windows, an overhead dome light, and much more.
One-Piece Hardtops

Jeep Soft Tops
Soft tops are where matters can get a little confusing.
To start, it is necessary to determine whether or not you have a pre-existing frame, and whether it’s in usable condition. Remember that the frame is the backbone of your soft top, and therefore a worn, rusted, or misshapen frame can cause your Jeep top to install improperly, or perhaps not perform as expected.
If you do have a frame already in place, you next need to find out if it’s a factory or aftermarket frame. This will ultimately help you narrow down which aftermarket Jeep top options are available to you, since certain Jeep tops are only compatible with particular frame styles.
For those without a Jeep top frame altogether, an aftermarket Jeep top kit that includes both the Jeep top and hardware system to set it up is suggested.
Pre-Existing Factory Frame Jeep Tops
These Jeep tops are designed exclusively for use with Jeep vehicles that have a pre-existing factory frame in usable condition.
Replace-A-Tops
For a fast, efficient, and inexpensive soft Jeep top solution, Replace-A-Tops make updating your old, worn factory top simpler than ever.
The Replace-A-Top is a basic Jeep top skin that easily slips on and off your factory frame. Each kit includes only the Jeep top fabric with optional clear or tinted windows, and the Jeep tops themselves are built to factory standards, or better.
Additionally, the Replace-A-Top includes a host of other fine features, such as premium fabric construction, mildew and UV resistant material, industrial strength thread, heat sealed seams, and much more.
Trusted Jeep tops manufacturers Bestop, Rugged Ridge, and Smittybilt each offer perfectly reliable and inexpensive Replace-A-Top models.
Bestop also offers a premium option in their Replace-A-Top Jeep top made out of revolutionary Sailcloth fabric to help improve insulation and drastically reduce road noise over factory Jeep tops.
Halftops
For a sporty two-seater look and feel there’s nothing quite like a Halftop Jeep top. Combining components of several other styles, the Halftop is the perfect hybrid of unique style and rugged function.
The Halftop includes all the usual soft top functions and Jeep accessories like mildew and UV resistant-fabric, a convenient fold back sunroof, zip-out windows, and much more, but then also incorporates all of this into an unconventional sporty look.
The Halftop Jeep Top from Bestop is actually something of an exception when it comes to having the right hardware for installation. It can accommodate those who have a pre-existing factory hard or soft top frame, or for those who have no frame at all.
Halftop Jeep tops are available exclusively from Bestop.
No Frame or Aftermarket Frame Jeep Tops
These Jeep tops are compatible with Jeeps that have either no soft top frame whatsoever, or a pre-existing aftermarket frame.
Supertop
You wouldn’t think from the sleek design and intuitive features that the Supertop Jeep top has followed mostly the same formula for decades.
Sold as a complete package with all necessary mounting hardware and Jeep accessories to get your started, a Supertop is a simple yet dependable solution for adding a soft top to an open-top Jeep. Its “Set-N-Stretch” fabric won’t fade or warp regardless of temperature, and the zip-out replaceable windows come in clear or tinted.
The Supertop also gives you a variety of other premium features like mildew and UV resistant fabric, industrial strength thread, heat sealed seams, heavy duty molded-tooth zippers for easy window installation and removal, and powder-coated rust-resistant frame hardware to ensure long frame life.
Best of all, using the Supertop framework, you can easily change out your top skin for a bikini top, or remove it altogether for open-air driving.
The Supertop Jeep top is available exclusively from Bestop, and is available in a complete kit with frame hardware or in replacement skins for those with an aftermarket frame already installed.
Rollback Sunroof Tops
These soft top Jeep tops follow the same basic formula of most other soft tops with the exception of a sleek and convenient rollback sunroof for a more open-air feel.
These Jeep tops also include all the necessary hardware you need to do a complete installation from scratch, and the versatile design also allows for compatibility with a number of soft door options.
Other features of Rollback Sunroof tops include mildew and UV resistant fabric, industrial strength thread, heat-sealed seams, heavy duty molded-tooth zippers for easy window installation and removal, and powder-coated rust-resistant frame hardware to ensure long frame life.
Current rollback sunroof-style Jeep tops include the Bestop Sunrider and Pavement Ends Flip Top.
Tiger Top
Vintage and classic Jeep owners need not feel left out thanks to the Tiger Top.
Designed and custom-crafted by Jeep tops leader Bestop, the Tiger Top Jeep top is built specifically for older model Jeeps, and even comes sporting that vintage Jeep look.
The Bestop Tiger Top includes all necessary hardware for a full installation onto an open top Jeep.
Your Jeep Top Purchase
Choosing a top isn’t as complicated of an affair as one might suspect. In the end, Jeep tops are all about getting the style you want at an agreeable price.
Hopefully this article has helped you in that decision-making process in order to minimize the hassle of buying and installing the right one so you can focus on the fun part.
Now go get your Jeep top.

Edge On Motorcycling- The BMW HP2 Sport
The BWM HP2 Sport is the latest iteration of the Bavarian Motor Company's foray into producing performance driven motorcycles. The quiet, staid, and lets just admit it boring motorcycles that came out of BMW in years past is history.
The HP line is BMW's new high performance, cutting edge line up. It's the motorcycle equivalent of their M line of performance cars.
The HP2 Sport is the third motorcycle in the HP line following the releases of the HP2 Enduro and the HP2 Megamoto.
The HP-2 Sport is based on the R1200S but is out and out designed for sports riders who are looking for a machine that has performance as well as endurance.
The HP2 Sport keeps some of the concepts that BMW motorcycles have become known for such as the BMW Motorrad Telelever front suspension and the EVO Paralever rear suspension. Other components have been newly developed or highly modified for use in the motorcycle.
The HP-2 Sport is powered by a twin Boxer motor that has a capacity of 1170 cc. The engine's cylinder heads were completely redesigned which allows the engine to rev as high as 9500 rpm. The engine has a 101 mm bore and a 73 mm stroke and produces a maximum of 130 hp at 8,750 rpm and 85 lb-ft of torque at 6,000 rpm.
The bike has a close ratio six speed gear box, with first and second gear having higher ratios. This puts the gear increments closer to each other and results in less of a rev drop when progressing up through the gears.
The bike also has a gear shift assistant which allows the rider to shift gears without using the clutch. It works by sensing when the gear lever is activated. If it senses gear lever activation without the use of the clutch, it electronically reduces power to the engine which puts the engine in a low load state and makes it possible to shift without the clutch. If the rider uses the clutch, the system becomes inactive.
The riding position of the HP-2 sport can be described as relaxed. BMW has extensive experience with endurance racing and knows that for racers to be fast over a long period staying power is more important than a full racer's tuck.
The dashboard was developed by 2D Systems, which also provides analytic recording systems to Moto GP racing.
The dashboard has two modes and is switched by two controls on the left handlebar. In road mode, typical information such as speed, rpm, time, and distance are displayed. In race mode data such as top speed, circuit times, number of gearshifts and rpm is shown.
The HP2 Sport will push BMW further into the world of performance motorcycling.
