An ACL patient is doing leg extensions to strengthen his quadriceps muscles. With no additional weight added, the patient's lower leg (shank+foot) has a mass of 6.25 kg. The center of mass of the lower leg segment is located 32 cm from the axis of rotation of the knee joint. The leg is flexed 25 degree down from horizontal. The quadriceps muscle acts through the patellar tendon, which inserts 5 cm from the axis of rotation of the knee joint...
the type of joint/range of movement and finally to determine how the bones, muscles and tendons work together to move about the joint. Materials: rubber tubing leg bones musculoskeletal model of the whole body tape Procedure: Examination of the KNEE and accompanying leg bones Carefully collect the three main bones of the knee. Lay the bones on the lab bench and place them in their proper positions to form a functional joint. Identify the following structures or where they would...
PROBLEM 2 Knee Extension - The angular motion of the lower leg about the knee joint, and the forces and torques produced by the muscles crossing the knee joint during knee flexions and extensions have been investigated by a number of researchers utilizing different experimental techniques. One of these techniques is discussed here. Consider the person illustrated in Fig. 10.12. The test subject is sitting on a table, with the back placed against a back rest and the lower legs...
Problem 3: The figure shows the sketch of a 2 degree-of-freedom (planar) robot arm, where the link 1 (i.e., the yellow link) and the link 2 (i.e., the pink link) are attached through a prismatic (sliding) joint which only allows for a relative translation. The joint O is equipped with a motor that supplies the external torque, t(t), whereas the joint A is equipped with a pneumatic actuator that supplies the external force, F(t). Mass centers of the links 1...
