Chapter 2: Stress & Strain...Axial Loading
Problems Solution
Problem 2.1 : An 80-m-long wire of 5-mm diameter is made of a steel with E = 200 GPa and an ultimate tensile strength of 400 MPa. If a factor of safety of 3.2 is desired, determine (
a) the largest allowable tension in the wire, (b) the corresponding elongation of the wire.
Problem 2.2: A steel control rod is 5.5 ft long and must not stretch more than
0.04 in. when a 2-kip tensile load is applied to it. Knowing that E = 29 X 106
psi, determine (a) the smallest diameter rod that should be used, (b) the corresponding normal stress caused by the load.
