the right angle ruler shown in the figure hangs from a peg . it is made of unifrom sheet metal. let lambda equal the leiner dinsity. one arm is Lcm long and the other is 2L cm long. find the angle theta at which it will hang in equilibrium

## Homework Equations

## The Attempt at a Solution

I believe ij ust sum the forces, that is the forces in the y direction equal zero as well as the torqs. i don't think i need the x right?

F(y) = 0 = P - .5mg - mg = P - .75mg

F(torque) = 0 = .5Amg - Bmg hwere A = .5LcosQ and B = LsinQ

F = 0 = .5(.5LcosQ)mg - (LsinQ)mg = .25cosQ - sinQ = 0

is this correct, how do i solve this
