    Forces Problem Please Help!!!!!!!!!!!!!!!!!!!!

    Ive got a question in this weeks homework that isnt in the text or anything...i think it is a torque problem but am not sure even where to start :confused:

    Its a drawing but the question asks

    What force will keep the lever from turning about point 0? Given A=45 cm, B=65 cm, the pull is 80 N, and angle is 30 degrees.

    The drawing it just a bar with a starting on the left side, 0 being where a and b join, and an angle labled pull at the other end.

    please help i have a test in 2 days haha

    thanks
