The force of friction, Mechanical Engineering

Assignment Help:

During paddling of a bicycle,the force of friction exerted by the ground on the two wheels is?

Ans) Since the rear wheel rotates by itself (we only paddle to rotate the fron wheel), the friction acts in backward direction which provides torque for the required rotation.But friction acts forward on front wheel as friction acts opp. to the direction of sliding or opposes the relative motion.
