ANSWER THE QUESTION NEATLY AND COMPLETELY

A spar buoy is a buoyant rod weighted to float and protrude vertically.
Suppose that the buoy is made of wood (SG = 0.6) , 2-in by 2-in by 15-
ft floating with a 5 Ibm of steel attached at the bottom. The steel
accidentally attached itself to a rock in the sea. Compute the angle e at
which the buoy will lean. Assume that the rock exerts no moment on
the spar.
