Homework Help: Uniform cantilevered beam?

  1. Feb 7, 2010 #1
    How do you go about doing this problem?

    For the uniform cantilevered bean 5 m long, which weighs 5N supporting a 10N force at the end, draw the free-body-diagram and calculate the force and moment from the wall.

    I also attached a picture.

    Hold a heavy book straight out for 10 minutes.

    Your "frame" supplies a vertical force at the shoulder socket which counters the weight force of the book and your arm. Your shoulder muscles supply a torque to your arm which counteracts the torques from your arm weight and the book weight. In your problem you have two torques and two weights which equal some torque and some force supplied by the wall.
