A brass tube with an outside diameter of 20 mm and 4 mm wall thickness is 80 mm long. It is joined to the end of a solid brass rod with a diameter of 20 mm and 120 mm long to form a compound assembly. This assembly is subjected to tension due to a mass of 150 kg moving at a speed of 0.4 m/s. 3.1. Determine the stresses induced in the rod and the tube respectively. 3.2. Determine the change in length of each part, as well as the total change in length of the assembly. 3.3 Determine the equivalent impact load (in kg) required to have the same effect (produce the same amount of energy) if falls freely from a height of 10 cm onto a collar attached to the bottom of the assembly if the assembly is vertically attached at its top.
