Forces on front wheel are, vertically upwards and frictional force in the forward direction
Forces on rear wheel are, vertically upwards and frictional force
weight of van lies at G = and is vertically downwards
net vertical force is zero.
so ------------(1)
The maximum acceleration occurs when front wheels are about to slip.
that is
-----------(2)
torques about center of gravity G ,
------(3)
using (1) and (3)
and
substituting value of in (2)

On the way to work, a person in a 6613.48 lb vehicle, with front-wheel drive, coasts down a 5.00 degree hill at constant velocity. (Neglect air resistance). A) Determine the static friction force, Ffrs, between the tires and the road. -On the way home, the same vehicle moves up the same hill, at constant velocity. B) Determine the static friction force applied by the front-wheel tires as it moves up hill at constant velocity to show that the static friction...
QUESTION 2 A rear-wheeldrive, 2-Mg truck has an acceleration of 37 m/sec2, starting from rest. The coefficient of static friction between the wheels and the road surface is 0.8.

Question 2. The all-wheel drive car shown in Figure 2 is at rest on a level road. The car's mass centre is at G. The car starts moving with an initial acceleration. For this car: (a) Draw the free body diagram showing all the forces acting on the car. (b) Assuming the coefficient of static friction between the tyres and the track is, for front tyres and Hz for rear tyres, obtain an expression for the maximum possible initial acceleration...
The tractor has a weight of 4500 lb with center of gravity at G. The driving traction is developed at the rear wheels B, while the front wheels at A are free to roll. If the coefficient of static friction between the wheels at B and the ground is s = 0.5 possible to pull at P = 1200 lb without wheels at B to slip or the front wheels the ground. 4 of 5 The tractor has a weight...

8. I drive a small sedan (a 2009 Toyota Yaris) that is front wheel drive. This means that the engine is linked only to the front wheels, so only the static friction coming from the front wheels can provide traction to help me move forward. 2 However, it has brakes on all four wheels, so static friction from both the front and the back wheels can provide traction to help me stop. Since the engine is the heaviest part of...
