Find total energy of the inclined rod of mass m shown in figure-5.39 , rotating with angular velocity `omega` , about a vertical axis XX', shown in figure .

A rod is rotating with angular velocity omega about axis AB. Find costheta .

The kinetic energy of a uniform rod of mass m rotating with constant angular velocit omega about one of its end which is fixed as shown in figure is (momega^(2)l^(2))/(N) find N

A small block of mass m is tied to the top of a smooth inclined plane with the help of a string of length L as shown in the figure. The inclined plane of inclination theta with horizontal is rotated with an angular velocity omega about a verticle axis passing through the end of the string fixed to the plane. (a) Find the maximum value of omega so that the block maintains contact with the inclined plane. (b) Find the ratio of the tension in the string and the normal reaction between the block and the plane.

A thin uniform copper rod length l and mass m rotates unifomly with an angular velocity omega about a vertical axis passing through one of its ends as shown in the figure. Young's modulus of copper is Y. Breaking stress is sigma_(max) , cross sectional area of rod is A and density of rod is uniform. Based on above information, answer the following questions The maximum angular velocity with which the rod can rotate so that is won't break, is
