A block with mass M is held statically on an overhang by a force Mg applied horizontally and the force of friction on the overhang. What are the normal and frictional forces? For what angles θ does the block remain at rest?
The Attempt at a Solution
In the picture I've drawn out the forces acting on the block. I understand the ideas behind static equilibrium. What I have trouble with is understanding which trig functions to use when comparing the forces and how to identify which angles are equivalent to the angle θ in the problem. Can anyone explain the thought process behind determining these things?
