A parking garage is designed for two levels of cars. To make
more money, the owner decides to double the size of the gar-
age in each dimension (length, width, and number of levels).
For the support columns to hold up four floors instead of
two, how should he change the columns’ diameter?
(a) Double the area of the columns by increasing their
diameter by a factor of 2.
(b) Double the area of the columns by increasing their
diameter by a factor of V2.
(c) Quadruple the area of the columns by increasing their
diameter by a factor of 2.
(d) Increase the area of the columns by a factor of 8 by
increasing their diameter by a factor of 2V2.
(e) He doesn't need to increase the diameter of the
columns.
The light boom AB is attached to a vertical wall by a ball
and socket joint at A and supported by two cables at B. A
force P is applied at B where P = 20i - 9j kN.Note that the
reaction force at A acts along the boom because it is a
two-force member. Calculate the magnitude of the
reaction force at A in kN.

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 ||Fill = ||F2l|| = T.
