38. A long, thin rod is cut into two pieces, one being twice as long as the
other. To the midpoint of piece A (the longer piece), piece B is attached
perpendicularly, in order to form the inverted “T" shown in the drawing.
The application of a net external torque causes this object to rotate about
axis 1 with an angular acceleration of 4.6 rad/s². When the same net ex-
ternal torque is used to cause the object to rotate about axis 2, what is the
angular acceleration?
