1. The PASCO human arm model is configured such that the cord representing the bicep is perfectly vertical and the forearm is at 90° (in the figure to the right, the cord is not quite vertical). A mass of 100 g is attached to the hand. Draw a free-body diagram on the figure to the right showing all forces which act on the forearm. The force of the bicep F on the arm The force of the humerus FH on the arm The weight of the forearm W The mass in the hand Wm 100 g Be careful to draw the force vectors with tails beginning at the point where the force is actually applied to the forearm. 2. Consider the free body diagram below. Determine the perpendicular component F̟ of the force F exerted by the biceps brachii on the forearm. Use the fact that cos 0 = H/B to write this component directly in terms of the humerus length H and the biceps length B. H 3. If the forearm is in equilibrium, then there is no angular acceleration and therefore the sum of the torques applied to the forearm must be…

The diagram models a juggler balancing a pole on her nose. The pole has length L and is modeled as a a mass-less rod with a point mass mp located at the distal end. The rod is attached via a friction-less pin to the cart Me. By moving her head (mass Me) she can correct any tendency for the pole to flop over. This is accomplished by supplying a force F to her head by neck muscles (not shown). This makes a nice 410 project, except that first we have to find the transfer function. Find the full non-linear dynamics equations. HINT: Use the energy method discussed in class. mp x(t) 0 Mc gl F
