Suppose you start an antique car by exerting a force of 300 N on its crank for 0.250 s. What angular momentum is given to the engine if the handle of the crank is 0.300 m from the pivot and the force is exerted to create maximum torque the entire time?

Step-by-step solution Step 1 of 3 The angular momentum given to the engine by the crank can be calculated as, Or, Here, is the net toque generated due to the force acting on the crank, is the required angular momentum and is the time for which the force is acted upon the crank. Step 2 of 3 The net torque is calculated as, Here, is the force exerted upon the crank and is the perpendicular distance from the crank. Substitute for and for r.
