A uniform cylinder of mass M, radius R is placed on a frictionless bearings and set to rotate about its axis with angular velocity w. After the cylinder has reached the specific state of rotation, it is heated from temperature T to (T+dT) without any mechanical contact. If dI/I is the fractional change in moment of inertia of the cylinder and dw/w be fractional change in the angular velocity of cylinder and A be the coefficient of linear expansion, then 1) dI/I = ? and also 2) dw/w = ?Ans - 1) 2dR/R2) -2AdTPlease I need the procedure
