Question
a F2 1 FR F1 b The figure above shows a crane tower on site at the HWY 1 expansion and Stoney Trail extension in NW Calgary. You are a design engineer working for the company supplying cranes for the contractors and you have been asked to evaluate the tower design. The crane tower supporting the pulley is designed so that the resultant force from the cable tension running over the pulley is oriented along the tower axis. Note: The tension in the cable is the same on both sides so l|F1|| = ||F2|| = T.
