A 100-mm-long rod has a diameter of 15 mm. If an axial tensile load of 100 kN is applied, determine its change in length. Assume linear elastic behavior with E = 200 GPa.

please explain in neat hand writing so I can undertstand

A structural member in a nuclear reactor is made of a aluminium. An axial load of 22 kN is to be supported by the member. Use a factor of safety of 3.5 relative to yielding. EAl = 100 GPa, σy = 400 MPa. The material has elastic behavior. What is the load on the member if it is 1 mm long and its elongation is 0.5 mm?

An aluminium rod is fixed at its base and free at the top as shown in Figure 1. If the imposed eccentric load is P = 200 kN, determine the greatest allowable length, L, of the rod so it does not buckle or yield. The elastic modulus of the material is 72 GPa and the yield stress is 410 MPa. 5 mm 200 mm Figure P L 1 (not to scale)
