lifeboat hangs

A lifeboat hangs from two ships’ davits, as shown in
the figure. A pin of diameter d 0.80 in. passes through
each davit and supports two pulleys, one on each side of the
davit.
Cables attached to the lifeboat pass over the pulleys
and wind around winches that raise and lower the lifeboat.
The lower parts of the cables are vertical and the upper
parts make an angle a 15° with the horizontal. The
allowable tensile force in each cable is 1800 lb, and the
allowable shear stress in the pins is 4000 psi.
If the lifeboat weighs 1500 lb, what is the maximum
weight that should be carried in the lifeboat?
