I really have no idea how to go about doing this one.... Any help is well appreciated! Thanks!!! What is the angular acceleration of the rectangle in (attachment) if a torque of 13 Nm is applied about (a) the x axis (b) the y axis and (c) the z axis (through origin and perpendicular to the page). I assumed I would use t=Ia where I would simply be m*r^2. But that gives me the wrong answer. The answers are (a)2.4 (b)5.1 (c)3.0 if that helps.
