Homework Statement
A uniform bar AB of length l and weight W is hinged to the wall at its end A and supported by means of a string of length a which is tied to the wall as shown. Find the angle [tex]\theta[/tex] that the bar will make with the wall corresponding to the position of equilibrium
Homework Equations
Moment = Force X perpendicular distance
The Attempt at a Solution
I had tried to find moment about point A. I had resolved W and T (tension in the string BC) into rectangular components. One along the bar and other perpendicular to the bar. along the bar components will not add to the moments at A while the perpendicular components will get multiplied by the distance (For T and W, l and l/2 respectively) and added according to sign convention (anticlock wise rotation as positive and clockwise rotation as negative). but because the angle ABC is getting too bulky (complicated), I don't think I can anyhow end this problem with answer. Need your immediate help.
