3D System in Equilibrium Example [Vector Statics #25]

Here we have a box suspended by two cables while two additional forces are pulling on it in the X and Z directions, respectively. The entire system is in equilibrium and we're asked to find the forces P and Q which act along the X and Z axes respectively.
