Question

An engineer determines that a 40-cm-long rod of 1020 grade steel will be
subjected to a tension of 20kN. The following two design requirements must be
met: The stress must remain below 145MPa, and the rod must stretch less than
0.125mm. Determine an appropriate value for the rod's diameter to meet these
two requirements. Round up to the nearest millimeter when reporting your
answer.​
