a. The anchor is shown (Figure 3) is used to tie tower guy cables to the ground and is supported by a distributed force from the soil, which can be approximated as shown. The anchor also is subjected to the loads shown, where P1 = 5 kN and P2 = 3 kN. The anchor is made from aluminum with E = 69 GPa. It is a cylindrical rod with a diameter of d1 = 4 cm with three segments of length L = 2 m. One end of the rod is linearly tapered to a diameter of d2 = 2 cm Use the reaction found in Part A, po = 13 kN/m, and calculate the total change in length for the anchor.
