WebThe work-energy theorem for a rigid body rotating around a fixed axis is. W AB = KB −KA W A B = K B − K A. where. K = 1 2I ω2 K = 1 2 I ω 2. and the rotational work done by a net force rotating a body from point A to point B is. W AB = θB ∫ θA(∑iτ i)dθ. W A B = ∫ … WebIf there are N turns, the =work Dis W = N F (πD) N M g (πD), where is the diameter of the cylinder. Thus W = (π)D .M g N (2) N is the number of turns the crack is rotated. Remember you are doing mechanical work against the friction. The work done by the friction adds the internal energy thereby increasing the temperature of the cylinder. black truck with red interior
