  1. Dec 9, 2008 #1
    1. The problem statement, all variables and given/known data

    Consider an example that will make use of a hinged rod supported by a rope. The rod has a mass of 1.4 kg, a length r, and there is an angle of 34 degrees between the rope and the rod. What is the tension the rope

    2. Relevant equations

    3. The attempt at a solution

    Fx = 0 = Hx-Tcos34
    Fy = 0 = Hy - Tsin34 - mg
    Net Torque = Tcos34(r) - Tsin34...????

    please help

    Is the rod horizontal? Is the rope attached at the end of the rod?

    If so, using the hinged end as the pivot, what torques act on the rod?
