Homework Statement


In the figure below, a uniform beam of length 12.0 m is supported by a horizontal cable and a hinge at angle θ = 40°. The tension in the cable is 600 N.


Homework Equations



T=F x r

The Attempt at a Solution


I attempted to calculate the net torque using all the forces(mg and tension), so 0=mgsin(40) - Tension.

Nevermind got it. Used mg(l of rod/2)sin(theta)-T*lcos(theta)

welcome to forum,
that's an easy problem. As the body is equilibrium net torque should be zero.
