Consider any wheel of an all-wheel drive car.
(a) For the case when the car is stationary, obtain the maximum
torque (moment) that the motor can apply to the wheel, without
causing it to slip on the ground. Obtain the expression in terms of
wheel diameter 𝐷, normal force between the wheel and the ground 𝑁,
and coefficient of static friction 𝜇𝑠.
(b) Now consider a case when the car is moving taking into account
the aerodynamic loads. Does the maximum torque that can be applied
to the tyre (without causing it to slip) change compared to part
(a)? Briefly explain why.
