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