A light rod of length l is pivoted at the upper end. Two masses (each m), are attached to the rod, one at the middle and the other at the free end. What horizontal velocity must be imparted to the lower end mass, so that the rod may just take up the horizontal position ?

A weightless rod of length l carries two equal masses m one fixed at the end and other in the middle ofhte rod. The rod can revolve in a vertical plane about A. Then, horizontal velocity which must be imparted to end C of rod to deflect it to horizontal position is

A ball of mass m is attached to one end of a light rod of length l , the other end of which is hinged. What minimum velocity v should be imparted to the ball downwards, so that it can complete the circle ?

A ball of mass m is attached to one end of a light rod of length l , the other end of which is hinged. What minimum velocity v should be imparted to the ball downwards, so that it can complete the circle ?

A light rod of length l is pivoted at distance l//4 from the left end and has two masses m_(0) and m attached to its ends such that rod is in equilibrium. Find m in terms of m_(0) .

A mass 2 m is fixed at one end of a light rod of length I . What horizontal velocity should be imparled to the lower end so that it may just take up the horizontal position ? If the mass is now rearanged with m at the lower end and the other m at the middle, what velocity is required ?

A weightless rod of length 2l carries two equal masses 'm' , one secured at lower end A and the other at the middle of the rod at B . The rod can rotate in vertical plane about a fixed horizontal axis passing through C . What horizontal velocity must be imparted to the mass at A so that it just completes the vertical circle.

A slender rod of mass m and length L is pivoted about a horizontal axis through one end and released from rest at an angle of 30^@ above the horizontal. The force exerted by the pivot on the rod at the instant when the rod passes through a horizontal position is
