3. From the results you obtained in this laboratory, compute the net muscle force in the biceps brachii necessary to maintain the forearm at a right angle relative to the upper arm using the centre of gravity values for the forearm segment obtained using Clauser, Dempster and Zatsiorsky's tables and given that the muscle inserts 5 cm from the elbow joint (think back to Lab 5 - Moments of Force). Assume that the muscle acts at 90° to the forearm and that there is not an additional weight in the hand. cg
