The problem(s) are shown in the link, but I'm having trouble getting them started.
Homework Equations
The Attempt at a Solution
For 3-12:
I think what I need to do is find the tension force in the ropes leading from each block to point A. Then with those forces I find the Sum of the forces in X and Y
From there i think i know what to do, its just that i don't know how to find the force in each rope!
My attempt:
For block B, the force in the the rope to point A is sin∅/200lb. For block C, the force in the rope to point a is sin(30)/100 =50lb .
Is this correct so far?
