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...
KIN 3112 Homework #3 Perform a dynamic analysis for a knee extension movement. The knee extensors insert on the tibia at an angle 0-30° and at a distance d-5.2 cm from the axis of rotation of the knee. The combined weight of lower leg and foot is F 48 N and its center of mass is r 0.27 m away from the knee joint axis. The joint angle with respect to the left horizontal is A-70 (Note: this is not...
Your next patient is a 66-year-old African American female complaining of right hip and knee pain. She states that her pain is most intense during the morning, upon arising from bed but tends to improve with movement. She states she “warms up” during the day, but if she overexerts himself, her morning stiffness is worse. On physical exam, you note tenderness at the right hip and knee with movement but no swelling or erythema. You examine her right knee and...
