A rod of length `l` is siding such that one of its ends is always in contact with a vertical wall and its other end is always in contact with horizontal surface. Just after the rod is relased from rest, the magnitude of acceleration of end points of the rod is and `b` respectively. The angular acceleration of road at this istant will be

A uniform rod of mass 20 Kg and length 1.6 m is piovted at its end and swings freely in the vertical plane. Angular acceleration of the rod just after the rod is relased from rest in the horizontal position is

A uniform rod of length 2l is placed with one end in contact with the horizontal table and is then inclined at an angle alpha to the horizontal and allowed to fall. When it becomes horizontal, its angular velocity will be

A uniform rod of mass m length l is attached to smooth hinge at end A and to a string at end B as shown in figure. It is at rest. The angular acceleration of the rod just after the string is cut is :

A uniform rod of length l and mass M pivoted about its end as shown in Fig. and is free to rotate in the vertical plane about the pivot. The rod is released from rest in the horizontal position. (a) What is the initial angular acceleration of the rod? (b) Find the initial acceleration of the right end of the rod? ( c) Find normal contact force due to hinge when rod has rotated through angle theta as shown in Fig.

A uniform rod AB hinged about a fixed point P is initially vertical. A rod is released from vertical position. When rod is in horizontal position: The acceleration of end B of the rod is

A straight rod of length 3l units slides with its ends A,B always on the x and y axes respectively,then the locus of the centriod of Delta OAB is

A rod of length I leans by its upper end against a smooth vertical wall, while its other end leans against the floor. The end that leans against the wall moves uniformly downward. Then:

A uniform rod of length 2L is placed with one end in contact with the horizontal and is then inclined at an angle a to the horizontal and allowed to fall without slipping at contact point. When it becomes horizontal, its angular velocity will be
