A person lifts a load of one-half body weight (body weight = 770 N). The joint positions and muscle attachment locations are measured, as shown in the figure, for the ankle, knee, and hip. Note that the Achilles tendon acts at an angle 35 degrees clockwise from vertical. The patellar tendon acts 45 degrees clockwise from vertical. The gluteus medius acts 15 degrees counter-clockwise from vertical. The points of actions of the Achilles tendon, the patellar tendon, and the gluteus medius are at point A, B and C respectively. Find the tendon force magnitude and the joint reaction forces (both magnitude and direction) at the ankle, knee and the hip joints (point D. E. and F. respectively). For this analysis, neglect the weight of the body segments, and assume that each leg is in the same configuration and bears equal load. Note the following distances: I a=18 cm e = 42 cm i=7 cm b = 15 cm f-35.5cm j= 14.75 cm c=5 cm g = 10 cm k = 10 cm d = 31 cm h = 10.5 cm B
