Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Wheelbase shopping experience:
1. Compare - without doubt the biggest advantage that the Wheelbase offers shoppers today is the ability to compare thousands of Wheelbase at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Wheelbase? Wrong! If the Wheelbase is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Wheelbase then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Wheelbase? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Wheelbase and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Wheelbase wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Wheelbase then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Wheelbase site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Wheelbase, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Wheelbase, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

In both road and rail
vehicles, the
wheelbase is the distance between the centers of the front and rear wheels.
Road
In
automobiles, the
wheelbase is the horizontal distance between the center of the front wheel, and the center of the rear wheel. At equilibrium, the total
torque of the forces acting on the car is zero, and thus the wheelbase is related to the weight on each tire by the following formulas:
W_f = {d_r \over L}mg
W_r = {d_f \over L}mg
where W_f is the weight on the front tire, W_r is the
weight on the rear tire, L is the wheelbase, d_r is the distance from the
center of gravity (CG) to the rear wheel, d_f is the distance from the center of gravity to the front wheel, m is the mass of the car, and g is the Standard gravity. So, for example, when one loads the trunk with heavy goods, the center of gravity shifts rearward and the weight on the rear tire increases causing it to sink depending upon the stiffness of the
suspension (vehicle).If the
automobile is accelerating or decelerating, extra torque is placed on the rear or front
tire respectively, and the equation relating the wheelbase, height above the ground of the CG, and the weight on each
tire becomes:
W_f = {d_r \over L}mg - {h_{cg} \over L}ma
W_r = {d_f \over L}mg + {h_{cg} \over L}ma
where W_f is the weight on the front tire, W_r is the weight on the rear
tire, d_r is the distance from the CG to the rear wheel, d_f is the distance from the CG to the front wheel, L is the wheelbase, m is the mass of the car, g is the acceleration of gravity (approx. 9.8 m/s2), h_{cg} is the height of the CG above the ground, a is the acceleration (or deceleration if the value is negative). So, as is common experience, when the automobile accelerates, the rear usually sinks and the front rises depending on the suspension (vehicle). Likewise, when braking the front noses down and the rear rises.:{{cite book| title = Introduction to Statics and Dynamics| last = Ruina| first = Andy| coauthors = Rudra Pratap| year = 2002| pages = 350| publisher = Oxford University Press| url = http://ruina.tam.cornell.edu/Book/RuinaPratapNoProblems.pdf| format = PDF| accessdate = 2007-03-23-->
Because of the effect the wheelbase has on the weight transfer of the vehicle, wheelbase dimensions are crucial to the balance and steering of the
automobile. For example, a
Automobile with a much greater weight load on the rear tends to
understeer due to the lack of weight and therefore grip from the front tires. This is why it is crucial, when towing a single-axle caravan, to distribute the caravan's weight so that down-thrust on the tow-hook is about 100 pounds force (400 N). Likewise, a car may
oversteer or even "spin out" if there is too much weight on the front
tires and not enough on the rear tires. Also, when turning there is lateral
torque placed upon the
tires which imparts a turning force that depends upon the length of the
tire distances from the CG. Thus, in a car with a short wheelbase, the short lever arm from the CG to the rear wheel will result in a greater lateral force on the rear tire which means greater acceleration and less time for the driver to adjust and prevent a spin out or worse.
Wheelbases provide the basis for one of the most common vehicle size class systems.
Bikes
The Bicycle and motorcycle geometry#wheelbase on many commercially available
bicycles and
motorcycles is so short, relative to the height of their
center of gravity, that they are able to perform stoppies and
wheelies.
Rail
In rail vehicles, the wheelbase follows a similar concept. It is particularly applied to
steam locomotives. Short-wheelbased locomotives can negotiate sharper curves. On some larger wheelbase locomotives, driving wheels may lack flanges in order to pass curves.
