When it says to express your answer in terms of W, does that include Wc, or can it only be in terms of W?
Nevermind, that was a dumb question
I think it wants the answer in terms of W only.
Does the angle at which the force of the disk pushes on the block have the same sine and cosine values as the angle on the block, except reversed?
I believe so, because the force of the disk acts perpendicular to the surface of the block that it acts on. I also think the magnitude force of the disk on the block is more than just the weight of the disk, because it also has to cancel out with a normal force from the wall.
