Suppose a person abducts the arm by holding a weight. The abduction happens because the deltoid muscle inserts into the deltoid tuberosity of the humerus (shoulder bone). A laboratory skeleton is chosen to identify the fulcrum, measure the effort and resistance arms, determine the mechanical advantage of abduction, and also to determine which type of lever the upper limb belongs when performing abduction.
