Use the principle of Strain energy due to direct stresses strength of materials 2 A 40 mm diameter rod of a certain material is 1,2 m long and has a collar fitted to one end. Therod is held vertically and a weight of 20 kN is gradually lowered onto the collar, producing anextension of 0,253 mm. Calculate the height from which this load could be dropped onto thecollar if the maximum stress in the bar is to be 100 MPa.
