Homework Help: Torque and Rotational Equilibrium

  1. Apr 10, 2006 #1
    Hi there,

    This is my first time on this great board, I hope I can get some help!

    I've tried both of these torque and equilibrium questions, but cannot find the required variable. (I've tried summing forces in the x and y)

    Please help!

    1) Find mass

    2) Find tension and reaction force on the hinge.

    Thanks in advance to everyone.

    Try summing moments. Sum of moments at any point is equal to 0 N*m
