Homework Help: How to calculate weight an arm can curl.

  1. Oct 16, 2011 #1
    1. The problem statement, all variables and given/known data
    Suppose the length of your forearm is 34cm and its mass is 1.3kg. If your bicep inserts into the forearm 3.5cm from the pivot (the elbow), and your biceps muscle can produce a force of 800 N, how much weight can you curl? Model your forearm as a uniform rod.

    I have no idea what to do!

    Please help!

    Thanks in advance!
