Explanation:

Given that:

The anchor shown 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 kNand P2 = 3 kN . The anchor is made from aluminum with E = 69 GPa . It is a cylindrical rod with diameter 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.

a. Calculate the intensity of the reaction load, Po

b. Use the reaction found in Part A, po = 13 kN/m , and calculate the total change in length for the anchor.
