A heavy iron bar of weight W is having its one end on the ground and the other on the shoulder of a man The rod makes an angle theta with the horizontal What is the weight experienced by the man ?

A rod of mass M and length L lying horizontally is free to rotate about a vertical axis through its end. A horizontal force F on the rod at the other end, the force always remains perpendicular to the rod. Find the angular velocity of the rod when it has turned an angle pi//2 .
