The 10-kg wheel has a radius of gyration about its center O of kO = 300 mm. When it is subjected to a couple moment of M = 50 N⋅m, it rolls without slipping.

Determine the angular velocity of the wheel after its center O has traveled through a distance of sO = 20 mm, starting from rest.

Express your answer to three significant figures and include the appropriate units.

A wheel of radius R rolls to the right with an angular velocity w. a) write the parametric equations that express the movement of a spot on the wheel that is a distance r<R from the center. Assume the point is at its maximum height at time t=0. b) suppose the wheel is pushed up a ramp that makes an angle X with the horizontal. Because it is being pushed it maintains its angular velocity w. Write the parametric equations...

A clutch plate initial consists of wheel A rotating about its body axis through the center of the wheel. Wheel B is initially at rest. Wheel A and B are then brought together so that they may be considered a single composite wheel turning with the same angular velocity. This causes the rotation to slow. We wish to find the final angular velocity given the following conditions: Mass of wheel A is 10 kg. Its radius is 3 meters. The...
