I have been stuck on this problem for the last half, and to be honest I don't even no where to begin. I'm being asked to calculate all of tensions for the cords. I know I'm supposed to use $\cos$ to calculate the $x$ tensions and $\sin$ to calculate the $y$ tensions, but that's about as far as I'm getting. Can someone please walk me through this and help me understand problem 51?

Welcome to Physics.SE, Scotty. We have a policy of not solving particular problems that might be homework, though we will answer questions on the conceptual basis of the problems. In this case you should notice that everyplace the cords connect---either to the weight, the ceiling or another cord---is static. Static means it is not accelerating which implies something very important about the forces working on that point. –  dmckee Feb 5 '13 at 5:15
