Homework Help: Torque Problem not yielding answer choices

  1. May 6, 2017 #1

    3. 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.

    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.
