Axial Load 1: The A992 steel rod is subjected to the loading shown (Pig1). If the cross-sectional area of the rod is 60mm², determine the displacement of B and A, Neglect the size of the couplings at B, C, and D.

Axial Load 2: The assembly consists of a steel rod CB and an aluminum rod BA, each having a diameter of 12 mm (Pig2). If the rod is subjected to the axial loadings at A and at the coupling B, determine the displacement of the coupling B and the end A. The unstretched length of each segment is shown in the figure. Neglect the size of the connections at B and C, and assume that they are rigid. E_ST = 200GPa; E_AL = 70GPa.

Axial Load 3: The assembly consists of two 10-mm diameter red brass C83400 copper rods AB and CD, a 15-mm diameter 304 stainless steel rod EF, and a rigid bar G (Pig3). If P = 5 kN, determine the horizontal displacement of end F of rod EF.

Axial Load 4: The rigid bar is supported by the pin-connected rod CD that has a cross-sectional area of 14 mm² and is made from 6061-T6 aluminum (Pig4). Determine the vertical deflection of the bar at D when the distributed load is applied.

Axial Load 5: The post is made of Douglas fir and has a diameter of 60 mm (Pig5). If it is subjected to the load of 20 kN and the soil provides a frictional resistance that is uniformly distributed along its sides of  w = 4 kN/m, determine the force F at its bottom needed for equilibrium. Also, what is the displacement of the top of the post A with respect to its bottom B? Neglect the weight of the post.
