So there's a spring attached to a wall and it's connected to the axle of a cylinder. The cylinder doesn't slip and the axle-spring attachment is frictionless. I'm suppose to solve for the frequency of the motion using newton's second law both translational and rotational form. I set up torque=(moment of inertia)*(angular acceleration) the problem is, the spring force will not exert anyi torque since it has a radius of zero so I'm not sure how to go about doing this problem. Any help would be appreciated! Thank you!
