Question

A ship’s spar is attached at the base of a mast
by a pin connection (see figure). The spar is a steel
tube of outer diameter d2 = 3.5 in. and inner diameter
d1 = 2.8 in. The steel pin has a diameter d =1 in., and
the two plates connecting the spar to the pin have a
thickness t = 0.5 in. The allowable stresses are compressive
stress in the spar, 10 ksi; shear stress in the
pin, 6.5 ksi; and bearing stress between the pin and the
connecting plates, 16 ksi.
Determine the allowable compressive force Pallow
in the spar.
