Homework Statement
A gate 4.00 m wide and 2.00 m high weighs 528 N. Its center of gravity is at its center, and it is hinged at A and B. To relieve the strain on the top hinge, a wire CD is connected to the gate at an angle of 30 degrees. The tension in CD is increased until the horizontal force at hinge A is zero. What is the tension in wire CD?
Homework Equations
ΣF=0
Στ=0
τ=r*F
The Attempt at a Solution
Fx=Tension(cos(30))
Fy + Tension(sin(30))=528
Tension(sin30)(4m)=528(2m)
Tension= 528N
This is very wrong, I am so lost and confused please help.
