Question

A long thin rod is cut into two pieces, one being as long as the other. To the midpoint of piece A, piece B is attached perpendicularly, in order to form the inverted "T" shown in the figure. The application of a net external torque causes this object to rotate about axis 1 with an angular acceleration of 3.6 rad/s2. When the same net external torque is used to cause the object to rotate about axis 2, what is the angular acceleration?
