A rod AB with mass of 2kg at B is held in horizontal position due to a force F as shown.The rod is free to rotate about A.Then F in N is?

A rod OA of mass 4 kg is held in horizontal position by a massless string AB as shown in figure. Length of the rod is 2 m . Find (a) tension in the string (b) net force exerted by hings on the rod. (g = 10 m//s^(2))

A rod is released from the horizontal position as shown. It is free to rotate about hinge. Find angular velocity of rod when it become vertical?

The thin rod shown below has mases M and length L. A force F acts at one end as shown and the rod is free to rotate about the other end in horizontal plane. Initial angular acceleration of the rod is :

A uniform rod of length L and mass m is free to rotate about a frictionless pivot at one end as shown in figure. The rod is held at rest in the horizontal position and a coin of mass m is placed at the free end. Now the rod is released The reaction on the coin immediately after the rod starts falling is

Two beads of mass 2m and m , connected by a rod of length l and of negligible mass are free to move in a smooth vertical circular wire frame of radius l as shown. Initially the system is held in horizontal position ( Refer figure ) If the rod is replaced by a massless string of length l and the system is released when the string is horizontal then :

A uniform rod of mass m and length l is fixed from Point A , which is at a distance l//4 from one end as shown in the figure. The rod is free to rotate in a vertical plane. The rod is released from the horizontal position. What is the reaction at the hinge, when kinetic energy of the rod is maximum?

One-fourth length of a uniform rod of mass m and length l is placed on a rough horizontal surface and it is held stationary in horizontal position by means of a light thread as shown in the figure. The thread is then burnt and the rod start rotating about the edge. Find the angle between the rod and the horizontal when it is about to slide on the edge. The coefficient of friction between the rod and surface is mu .

A uniform rod AB of mass 2 kg is hinged at one end A . The rod is kept in the horizontal position by a massless string tied to point B . Find the reaction of the hinge (in N ) on end A of the rod at the instant when string is cut. (g = 10 m//s^(2))
