A load of 10 kg is held in one hand, with the lower arm horizontal. The lower arm has mass 1.5 kg The distance from the elbow to the hand is 30 cm and the COM can be assumed to be 40% of this distance (from E to H). a) What is the external static elbow moment? (31.2 Nm) b) If the biceps muscle acts with a perpendicular moment arm of 5cm, what force must it generate in order to...

Definitions and Equations: Moment of Inertia (D): Tendency to resist angular acceleration; the angular equivalent of mass. In practical terms it is a measure of how hard it is to rotate an object or segment, like a baseball bat or a body segment. It is the sum of the products of the mass (m) with the square of its distance from the axis of rotation (ka). SEE FINAL TWO PAGES OF THIS LAB EOR CHARTS NEEDED TO CALCULATE L. 1...
