A uniform rod is placed on two spinning wheels as shown in figure. The axes of the wheels are separated by a distance `l=20 cm`, the coefficient of friction between that in this case the rod performs harmonic oscillations. Find the period of these oscillations.

A uniform rod of length L and mass M has been placed on a rough horizontal surface as shown in the figure. The rod is pulled by applying a horizontal force. The coefficient of friction mu between the surface and the rod is given by mu = {(mu_(0)x, 0 le x le L),(0, x > L):} , where mu_(0) is a positive constant. The heat generated due to friction as the rod moves by a distance L is
