In a children's park a heavy rod is pivoted at the centre and is made to rotate about the pivot so tht the rod always remains horizontal. Two kids hold the rod near the ends and thus rotate with the rod figure. Let the mas of each kid be 15 kg, the distance betweent eh points of the rod where the two kids hold it be 3.0 m and supose that teh rod rotates at the rate of 20 revolutions per minute. Find the force of fircton exerted by te rod on one of the kids.

A particle is attached to an end of a rigid rod. The other end of the rod is hunged and the rod rotates always remaining horizontal. Its angular speed is increasing at contant rate. The mass of the particle is m . The force exerted by the rod on the particle is vecF , then:

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 .

A uniform rod of length L and mass M is free to rotate about a frictionless pivot at one end. The rod is released from rest in the horizontal position. What are the initial angular acceleration of the rod and the initial linear acceleration of the right end of the Rod ?

A rod of length L is pivoted at one end and is rotated with as uniform angular velocity in a horizontal plane. Let T_1 and T_2 be the tensions at the points L/4 and 3L/4 away from the pivoted ends.

A thin uniform rod is free to rotate about a fixed smooth horizontal axis as shown. A point mass hits horizontally with velocity v_(0) to the one end B of the rod. When it hits, it sticks to the rod, then :

A homogenous rod XY of length L and mass 'M' is pivoted at the centre 'C' such that it can rotate freely in vertical plane. Initially the rod is in the horizontal position.
