A tensile force. of 120 kN is applied on a 0.02-m diameter and 2-m long rod. After applying the load, the diameter decreases to 0.01998 m and the length increases to 2.01 m. The true stress on that rod is?
An engineer determines that a 32 cm long rod of 1020 grade steel will be subjected to a tension of 40 kN. The following two design requirements must be met: the stress must remain below 120 MPa, and the rod must stretch less than 0.135 mm. Determine an appropriate value for the rod's diameter to meet these two requirements. (Round up to the nearest millimeter when reporting your answer.) mm
