Diagram of a uniform beam of mass m pivoted at its lower end, held at angle θ to the horizontal by a horizontal tension wire T at the top, with multiple-choice answers A through E below.

The Attempt at a Solution



I took the pivot point to be the hinge point and calculated the torque to the force of gravity as well as tension. So

T=Ia=0=L*T*sin(180-θ)+(L/2)*F g *sin(θ) which yields

T+(1/2)F g=0 so shouldn't T=mg/2? However, this is not an answer choice.[/B]
 
Hello. Welcome to PF!

Be careful with constructing the trig function for the torque of Fg.

Wow thank you, I should have been more organized with how I drew my angles and parallel lines. I see it now.
