II. 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 μg. (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. Suggested time: 10 minutes. [6 marks] [4 marks]
