Two wheels have the same mass and radius of 48 kg and 050 m, Ask an Expert

Academics

Two wheels have the same mass and radius of 4.8 kg and 0.50 m, respectively. One has

(a) the shape of a hoop and the other

(b) the shape of a solid disk.

The wheels start from rest and have a constant angular acceleration with respect to a rotational axis that is perpendicular to the plane of the wheel at its center. Each turns through an angle of 13 rad in 9.4 s. Find the net external torque that acts on each wheel.
