Two identical small balls are suspended by ends of a rod. Whole assembly is rotating about vertical axis passing through center of rod. At a certain value of `omega` both strings make 37° with vertical. Find `omega`

A uniform metal rod is rotated in horizontal plane about a vertical axis passing through its end at uniform rate. The tension in the rod is

A rod of mass M and length l attached with a small bob of mass m at its end is freely rotating about a vertical axis passing through its other end with a constant angular speed omega . Find the force exerted by the system (rod and bob) on the pivot. Assume that gravity is absent.

Find the moment of inertia of thin and massless rod about an axis passing through its centre of mass of rod and pair of mass is suspended on both end of this rod.

A uniform rod of length l and density rho is revolving about a vertical axis passing through its one end. If omega is the angular velocity of the rod then the centrifugal force per unit area of the rod is

Two balls of masses m_(1) = 0.5 kg and m_(2) = 0.3 kg are connected by a nonstretchable string and slipped on to a horizontal , light rod. The rod is rotated with omega = 110 rpm about a vertical axis passing through its centre. Find the tension of the string and the distance of the masses from the axis of rotation if l=20 cm is the length of the string. Is the equilibrium of the balls stable ?

A uniform rod of mass m and length L lies radialy on a disc rotating with angular speed omega in a horizontal plane about vertical axis passing thorugh centre of disc. The rod does not slip on the disc and the centre of the rod is at a distance 2L from the centre of the disc. them the kinetic energy of the rod is

A uniform rod of mass m and length l_(0) is rotating with a constant angular speed omega about a vertical axis passing through its point of suspension. Find the moment of inertia of the rod about the axis of rotation if it make an angle theta to the vertical (axis of rotation).
