A wheel is rotating freely at an angular speed of 800 rev/min on a shaft whose rotational inertia is negligible. A second wheel initially at rest with thrice the rotational inertia of the first is suddenly coupled to the same shaft. The fraction of original kinetic energy lost is

A wheel is rotating with frequency of 500 rpm on a shaft, second identical wheel initially at rest is suddenly coupled on same shaft. The frequency of the resultant combination is

A wheel is rotating with frequency of 500 rpm on a'shaft, second identical wheel initially at rest is suddenly coupled on same shaft. The frequency of the resultant combination is

A wheel is rotating with an angular speed of r.p.m on a shaft. Second identical wheel axially at rest is suddenly coupled on the same shaft. What is the angular speed of the resultant combination ?Assume M.I of shaft to be negligible.

A wheel is rotating with a speed of 500 rpm on a shaft. Second identical wheel, initially at rest is suddenly coupled on the same shaft. What is the speed of the resultant combination ? Assume that the moment of inertia of the shaft is negligible.

A wheel of moment of inertia 0.10 kg-m^2 is rotating about a shaft at an angular speed of 160 (rev)/(min) . A second wheel is set into rotation at 300 rev/minute and is coupled to the same shaft so that both the wheels finally rotate with as common angular speed of 200 rev/minute. Find the moment of inertia of the second wheel.
