wearing a standard walking prosthesis and computer simulation of the flexing of the knee on this walking prosthesis. They had to measure rotation, weight bearing, moments, and the stress of the joints acting on this limb. After the mechanical actions were mapped out they had to use many mathematical equations to spring force and spring stiffness. All of this was accomplished and the conclusion was that by varying the placement and orientation of the spring, the moment arm values could be adjusted in an attempt to linearize the spring stiffness.
is also used in the study of sports actions, such as the motion of throwing a baseball. This process involves three major steps. First, an engineer must take photos of every separate motion in the release. Also the ground must be fitted with sensors to effectively sense the affects of a player upon the ground. Second, the engineer must determine the kinematics from marker positions, which involves drawings and calculations to find ...
