Thank you collinsmark! I'm very grateful for your welcome.
I think i understand now.
sum forces in x: Fx=T
sum forces in y: Fy+T=W/2
because we can assume that the weight is distributed half and half between A and B, right? and then, for finish we need only realize that: tan(theta)=Fy/Fx
Then we...
Homework Statement
A thin rod AB of weight W is attached to two blocks A and B that slide freely in the railways represented. The blocks are linked by a string inextensible and without weight passing through a pulley C.
Express the tension in the string in function of W and the angle θ that...
