The L-shaped object described in Problem 15 can be rotated in one of the following three ways: case A, about the x axis; case B, about the y axis; and case C, about the z axis (which passes through the origin perpendicular’ to the plane of the figure). If the same torque r is applied in the of these cases, rank them in increasing order of the resulting angular acceleration. Indicate ties where appropriate.
Problem
The L-shaped object in consists of three masses connected by light rods. What torque must be applied to this object to give it an angular acceleration of 1.20 rad/s2 if it is rotated about (a) the x axis, (b) the y axis, or (c) the z axis (which is through the origin and perpendicular to the page)?
