The mass of the T-bar shown is m=7.8kg. The T-Bar is pinned as shown. You may assume that the two sections (Horizontal and vertical) of the T-bar have the same mass per unit length.
L1=0.53m and L2=0.51m

a) At what value of is the centre of mass of the T-bar (measured downward from the centre of rotation)?
(Figured this out to be 0.3950m)

b) What is the moment of inertia of the T-bar (I) with respect to its centre of roration? (?)

c) What is the moment of inertia of the T-bar with respect to its centre of mass? (?)
