Unformatted text preview: ME 577 – Human Motion Kinetics Homework #6 Due 28 March, 2011 1. Using the data supplied in the file, pitching_data.xls, calculate the forces exerted at the wrist, elbow and shoulder (don’t worry about calculating the moments right now – but you should include them in your free body diagram).

You are given the position data so you will have to numerically differentiate in order to determine the velocity and acceleration. Please include the following plots: 1a) Velocity of the center of mass for the humerus, forearm, and hand vs. time. 1b) Acceleration of the center of mass for the humerus, forearm, and hand. 1c) Magnitude of the distraction force at the shoulder vs. time. 1d) Magnitude of the total force at the shoulder, elbow, and wrist vs. time....
