Chapter 17, Problem 17.35SP
A steel link in a machine is designed to avoid interference with other moving parts. The link is 100 mm thick. The cross-sectional area of the link is reduced by one-half at section A-A as shown. Compute the maximum tensile stress developed across section A-A. Neglect any stress concentrations.

The rigid bar AB of negligible weight is supported by a pin at 0. When the two steel
rods are attached to the ends of the bar, there is a gap D= 4 mm between the lower
end of the left rod and its pin support at C. Compute the stress in the left rod after
its lower end is attached to the support. The cross-sectional areas are 300 mm2 for
rod AC and 250 mm2 for rod BD. Use E= 200 GPa for steel.

A steel rod 20 mm in diameter passes centrally through a steel tube of 25 mm internal diameter and 30 mm external diameter. The tube is 800 mm long and is closed by rigid washers of negligible thickness which are fastened by nuts threaded on the rod. The nuts are tightened until the compressive load on the tube is 20 kN. Calculate the stresses in the tube and the rod.Find the increase in these stresses when one nut is tightened by one-quarter of a turn relative to the other. There are 4 threads per 10 mm. Take E = 2 x 105 N/mm2.
The structure shown below is hinged to fixed supports at A and C. The bars are each 4 in. by 4 in. in section. Compute the maximum
tensile stress developed in bar CB assuming the pin connections at A, B, and C are frictionless.
