A steel tower of a suspension bridge is designed to stand 250 feet tall. The forces from the cables create an average compressive stress in the tower of 50% of its yield stress. The tower is made from high strength steel, with Fy = 100 ksi, and E = 30,000 ksi. What is the loss of height under load (ie. shortening) that we can expect? (Hint: you don't need the area of the tower..) T Tower L=250' (76.2m) water level foundation
