A disc of radius r is connected to a string of length L. The string is tied to a point on the circumference of the disc. This system is made to oscillate in vertical plane of the disc with a small angular amplitude `theta_(0)`. Find the speed of the lowest point of the disc at the moment the string become vertical.

A disc of radius R is pivoted at its rim. The period for small oscillations about an axis perpendicular to the plane of disc is

A disc of mass M has a light, thin string wrapped several times around its circumference. The free end of string is attaced to the ceiling and the disc is released from rest. Find the acceleration of the disc and the tension in the string.

A long cylinderical rod is welded to a thin circular disc of diameter 0.5 m at a point on its circumference. The rod is in the same plane as that of the disc and forms a tangent to the disc. The radius of gyration of the disc about the rod (in m ) is

A string is wrapped on a uniform disc and the other end of the string connected to a wall. The system is placed on a smooth plane, inclined at an angle theta , with the string parallel to the plane, as shown in the figure. The acceleration of the disc is

A body of mass 40 kg is tied at one end of a string of length l. The body is oscillating in a vertical plane with angular amplitude theta_0 . What is the tension in the string when it makes and angle theta with the vertical ? If the breaking load for the string is 80 kgf, what can be the maximum angular amplitude of the body ?

A stone tied to a string of length l is whirled in a horizontal circle at a constant angular speed omega in a circle of radius r. If the string makes an angle theta with vertical then the tension in the string is :
