Chapter 4.9, Problem 4.101P
The rigid lever arm is supported by two A-36 steel wires having the same diameter of 4 mm. If a force of P = 3 kN is applied to the handle, determine the force developed in both wires and their corresponding elongations. Consider A-36 steel as an elastic perfectly plastic material.

The rigid beam is supported by three 25-mm diameters A-36 steel rods. If the beam supports the force of P = 230 kN, determine the force developed in each rod. Consider the steel to be an elastic perfectly plastic material.
The rigid beam is supported by three 25-mm diameter A-36 steel rods. If the beam supports the force of
P=230 kN, determine the force developed in each rod. Consider the steel to be an elastic perfectly
plastic material.
Detailed solution
The force P is applied to the bar, which is made from an elastic perfectly plastic material. Construct a graph to show how the force in each section AB and BC (vertical axis) varies as P (horizontal axis) is increased. The bar has cross-sectional areas of 1 in2 in region AB and 4 in2 in region BC. Take sY = 30 ksi.
