Document Summary

Kinematics- describing motion (what happens to object when kinetics are applied) Most appropriate movements to achieve mechanical purpose (mp) aka overall performance. Most appropriate sequence of movements (e. g. large parts then small parts) Answer questions # 1,3,5,6 on page 6. Answer questions # 1,3,4,5,6 on page 22. Skull pelvis: skull- 29 bones, thorax- 12 x 2 ribs and sternum, vertabrae. Each vertebrae is a bone with an articulation so easy to injure. Pelvis toes and shoulder fingers: upper extremities- shoulder to carpals. 32 x 2 (right to left: lower extremities- pelvis tarsals. Note- alignment is key in biomechanics; it keeps everything moving properly. Levers and pulleys for muscle torques: levers- flexion and extension- foul shot (shoulder flexion, pulleys- wheel axel system muscle pulls on bone (axis) and bone rotates. Tennis serve or football throw- overarm tosses. Kickers- planted foot is axel, other leg is wheel. If weight is too heavy, lever needs to be used.
