Your Question:
A spare buoy is a buoyant rod weighted to float and protrude vertically, as shown in the
figure below. Suppose that the buoy is made of maple wood ( , 0.6specific gravity s = ), has a
rectangular cross section ( 2.54 2.54cm by cm ), a length of 3.7 m , and is floating in seawater
( , 1.025specific gravity s = ). What weight of steel should be added to the bottom end of the
buoy so that 45h cm= ? ( , 7.85The specific gravity of steel s = ) (Answer: 8.1steelW N= ).
