They are the same size. BIG
The wheelbase is the distance between the front and the back wheels
Not one single person invented it, but it was developed from past trucks as far back as the 1700s. A Frenchman tried to make a steam-powered truck with a single front wheel and two back wheels with the boiler on the front. It ultimately failed but in the 1900s trucks were greatly improved.
Back
The back wheels are the only wheels that actually move. The front wheels are the wheels that steer.
many! there is no exact number as people create more
If the tractor trailers has duels only. You have 18 weels. (10 on front 8 on back) If the tractor trailers has super singles only, you got 10 wheels (6 wheels on the front and 4 on the back) If the trailer has super singles only, you have 14 wheels, (tractor has 10 wheels and trailer has 4) If your tractor has super singles only you looking at having, 14 wheels (6 wheels on the front 8 on the back)
The engine is located in the back of the truck.
If the back wheels slip / spin it automatically will transfer some of the power to the front wheels
Yes, it can be 2 wheels in the back and 1 wheel in the front. Its kind of like a training wheels with a wheel in the front/tricycle. An example is the Reliant Robin.
Means that you have the capability of locking your front or back hubs allowing you to havenall wheel drive. or 4 x 4. it means all 4 wheels spin not just 2
3 2 on the back and one on the front
All modern mass-produced cars and light trucks DO have hydraulic brakes on the front and the rear wheels. Heavy trucks generally have air brakes on all the wheels. Maybe you are thinking of cars that have disk brakes on the front and drum brakes on the rear? On cars, these are both hydraulically operated using the same hydraulic (brake) fluid. In normal stopping situations, the front brakes do more work than the rear brakes. Maybe 70 or 80% of the braking is done by the front wheels (it depends on where the weight is in the car and how fast you stop). Disk brakes are a somewhat better brake for a car, but drum brakes are a little cheaper to manufacture. So, disk brakes are almost always used on the front wheels where the braking is more important. Drum brakes are used on the back of some cars to save money. Note that performance cars (sports cars) almost always have disk brakes on all of the wheels.
