A pedestrian bridge is to be suspended using round rods. It is calculated that the load on each rod will be 2,057 N. If the yield stress of the metal used for the rods is 297 MPa, and a safety factor of 3 is required, the minimum area (mm^2) of each rod is?
A metal rod is 7.39 mm in diameter and 120 mm long before being loaded in tension. When subjected to a force of 1.5 kN, it will undergo 0.1% strain. What is the length of the rod (mm) in this loaded condition?
ps: I think this related to engineering stress and true stress?2 AnswersPhysics3 months ago
