## 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 forms the bar and the horizontal.

## Homework Equations

sum of the moments respect to C:

W*cos(theta)*L/2+Fx*sin(theta)*L+Wa*cos(theta)*L-Fy*cos(theta)*L=0

where L is the length of the rod and F the reaction of the rod.

sum of forces in horizontal and vertical:

Fx=T

Fy=Wa+W

is this correct?

## The Attempt at a Solution

The solution from the professor is T=W/(2*(1-tan(theta)) and the one i find is: T=W/(2*tan(theta)) similar, but not the same. Help please! thank you so much.
