January 16 th , 2008 BIOM 322 Biomechanics and Biotransport Homework #1 (Due at the start of class on January 23 th ) 1. A 60 kg person is preparing to dive into a pool. The diving board has a mass of 50kg and is mounted to the ground at point O. The weight of the diver can be assumed as a concentrated force applied on the diving board at point A. The distance form point O to A is 4 meters. a. What is the moment generated about point O due to the weight of the diver? b. What is the moment generated about point O due to the weight of the board? c. What is the net moment about point O? 2. For the exercise shown below, the quadriceps muscle works against the moment

Pick a few points and plot M O as a function of the angle θ from 0 to 90 degrees. A O 3. Determine the moment acting on the wrist ( M p ) due to the force of the tennis ball hitting the racquet. The distance from the point of impact to the wrist is 500mm. The weight of the racquet can be ignored. P 500mm 60˚ F= 60N 30˚ Racquet...
