A thin, cylindrical rod ℓ = 27.0 cm long with a mass m = 1.20 kg has a ball of diameter d = 10.00 cm and mass M = 2.00 kg attached to one end. The arrangement is originally vertical and stationary, with the ball at the top as shown in the figure below. The combination is free to pivot about the bottom end of the rod after being given a slight nudge.

Calculate the M.I of flywheel in moon having flywheel mass 21kg, diameter 20cm and mass of rings 600g, diameter of axle at 3.2cm, no. of chord 5 and hence find its K.E.

A cylindrical rod of mass 0.82 kg and length 1.88 m is free to rotate about a pivot fixed at one end. A ball with a mass of 3.2 kg is attached to the other end of the rod. The rod-and ball system is held in a horizontal position by a vertical force that acts 1.41 m from the pivot. The force is then removed, and the rod-and-ball swings down. (a) What was the vertical force used to hold the...

A cylindrical rod of length 2.0 m, radius 0.5 m, and mass 1.5 kg has two spheres attached on its ends. The centers of the spheres are 1.0 m from the center of the rod. The mass of each sphere is 0.66 kg. The rod is capable of rotating about an axis passing through its center and perpendicular to the plane of the page, but the set up is stationary to begin with. A small mass of value 0.19 kgmoving...

A rod 2 m long, 2 cm in diameter and 5 kg in mass is fixed at one end and is stricken by a force F to produce a 3rd overtone and elongates at 1 cm. A string of length L and mass 750 grams is puled by a T = 30 to produce a 3rd harmonic frequency. Determine the force F and length L that produces the same value of frequencies in the two materials, if the sound wave...

The figure shows a rigid assembly of a thin hoop (of mass m = 0.14 kg and radius R = 0.11 m) and a thin radial rod (of length L = 2R and also of mass m = 0.14 kg). The assembly is upright, but we nudge it so that it rotates around a horizontal axis in the plane of the rod and hoop, through the lower end of the rod. Assuming that the energy given to the assembly in...
