Consider two wheels with fixed hubs. the hub cannot move, but the wheel can rotate about it. the hubs are fixed to a stationary object. the hubs and spokes are massless, so that the moment of inertia of each wheel is given by i = mr2 , where r is the radius of the wheel. each wheel starts from rest and has a force applied tangentially at its rim. wheel a has a mass of 1.0 kg, a diameter of 1.0 m, and an applied force of 1.0 n. wheel b has a mass of 1.0 kg and a diameter of 2.0 m. the two wheels undergo identical angular accelerations. what is the magnitude of the force applied to wheel b?
