Problem 1 summarizes adjusting a steel wire so there is a 1/16 inch gap between a beam and contact point, and asks to determine where a 50 lb block should be placed to cause contact. Problem 2 describes steel links in a rigid member subjected to a 600 lb force, and asks to calculate the force in each link and the deflection of point A. Problem 3 involves steel bars reinforcing a brass bar subjected to a 25 kN load, and asks to determine the temperature increase needed to fit the steel bars and the stress in the brass bar.
