A steel pad supporting heavy machinery rests on four short, hollow, cast iron piers (see figure). The ultimate strength of the cast iron in compression is 400 MPa. The total load P that may be supported by the pad is 900 kN. Using a factor or safely 3.0 with respect to ultimate strength, determine the outer diameter of the pier if the thickness, is of the cross section is 12 mm.
In the figure shown, the cutaway view shows a solid aluminum alloy of L= 600mm, A= 707mm^2 and E= 70GPa rod within a closed-end bronze of L= 610mm, A= 1206mm^2 and E= 100GPa tube. Before the load P is applied, there is a clearance of 2mm between the rod flange at B and the tube closure at A. After load P is applied, the solid aluminum alloy rod stretches enough so that flange B contacts the closed end of the tube at A. If the load applied to the lower end of the aluminum rod is P= 345KN, calculate:A. The normal stress in bronze tube, in MPa.B. The elongation of bronze tube, in mm.

A uniform beam, 1.5 metre long, is suspended in a horizontal position by two vertical support rods as shown in the figure below. Rod A has a diameter of 12 mm and manufactured from steel with Esteel = 210 GPa. Rod B has a diameter of 16 mm and is made from copper with Ecopper = 105 GPa.

Two steel bars (Es = 200 GPa, αs 11.7 x 10-6/°C) are used to reinforce a brass bar (Eb=105 GPa, αb = 20.9 x 10-6/°C) that is subjected to a load P = 25 kN. When the steel bars were fabricated, the distance between the centres of the holes that were to fit on the pins was made 0.5 mm smaller than the 2 m needed. The steel bars were then placed in an oven to increase their length so that they would just fit on the pins. Following fabrication, the temperature in the steel bars dropped back to room temperature. Determine (a) the increase in temperature that was required to fit the steel bars on the pins, (b) the stress in the brass bar after the load is applied to it.
