A bar of mass m lies on a table attached to a stationary point O, with a non deformed elastic thread of length lo. The table was moved slowly on the floor till the bar started to slip when the thread made an angle theta with the vertical. If the coefficient of friction between bar and floor is k, find the work done by static friction acting on the bar till it started to slip, in the reference frame attached to the floor.
