Rotation about a Fixed Axis - Conceptual Example 6.6-1

 

Consider two bicycle wheels each having a mass of 1 kg. If both wheels start from rest and forces are applied as shown, how large must F₂ be if both wheels are to have the same angular acceleration? Assume that both wheels rotate about a fixed axis passing through the hub and that most of the mass is concentrated on the outer rim of each wheel. (I_wheel = mr²)
