The L-shaped object in Figure 11-27 consists of three masses connected by light rods. See attached Figure.

(a) What torque must be applied to this object to give it an angular acceleration of 1.27 rad/s2 if it is rotated about the x axis?
_________N?m
(b) What torque must be applied to this object to give it an angular acceleration of 1.27 rad/s2 if it is rotated about the y axis?
_________N?m
(c) What torque must be applied to this object to give it an angular acceleration of 1.27 rad/s2 if it is rotated about the z axis (which is through the origin and perpendicular to the page)?
