Homework Help: Calculating torque, force and angles

  1. Mar 23, 2012 #1
    1. The problem statement, all variables and given/known data
    A lever is used to lift a box, ignore the mass. the lever makes a 43° angle at the pivot, point A, the length of the lever is 1,8 m, Force P is apply 15° at the end of the lever
    Force P causes a moment of 500N.m about point A. Determine the force P?

    2. Relevant equations


    3. The attempt at a solution

    When using your formula for Torque, theta is the interior angle in between the force vector and the lever. Without a sketch, I don't know if you correctly determined theta. Welcome to PF!
