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 ||F1l|| = ||F2|| = T.
%3D
a) (LO2-4) If b = 1 (i.e. the anchor side of the cable is at a 45° angle), what should be the
slope a of the tower? What is the angle a of the tower?
(LO1-4) Write a relationship for the slope a of the tower in terms of the slope b of the
anchor side of the cable (i.e. write a = f(b)). [Hint: Define tan a = a and tan ß = b as the
relationship between slope and angle of the components.] Check your result from (a)
using this relationship.
