Question
A cylindrical structural element is made of steel. The element must withstand an axial load of 160 kN.
Determine the diameter of its cross section so that it does not have plastic deformation. What is the load that this element resists if it is 80 cm long and suffers an elongation of 200 micrometers?
Consider an elastic modulus of 200 G Pa. And a yield stress of 340 M Pa. Use a factor of safety of 3/5 with respect to the yield stress.
