Question
Problem 9.2
A 1200 kg mass is hanging from a small pulley that is free to
roll on the cable (frictionless, of course). The length of the
cable BC is 18 m. Determine the horizontal force (i.e., P) that
would hold the pulley in equilibrium in the position at x = 5 m.
Use COLM principles to solve. You must draw a KD and a FBD
for this closed, steady state (i.e., equilibrium) system.
Hint: Use LBC and geometry to find the angles of AB and BC
(relative to Pulley B).
