Question

A square steel tube of a length L = 20 ft
and width b2 =10.0 in. is hoisted by a crane (see figure).
The tube hangs from a pin of diameter d that
is held by the cables at points A and B. The cross
section is a hollow square with an inner dimension
b1 = 8.5 in. and outer dimension b2 =10.0 in. The
allowable shear stress in the pin is 8,700 psi, and
the allowable bearing stress between the pin and the
tube is 13,000 psi.
Determine the minimum diameter of the pin in
order to support the weight of the tube. Note: Disregard
the rounded corners of the tube when calculating
its weight.
