Assignment task:
Ankle Joint Forces During Walking: A person is walking with a ground reaction force of 2 times body weight (1400 N) acting at a 20° angle to the vertical. The Achilles tendon exerts a force of 1000 N at a 60° angle to the horizontal. Calculate the joint reaction force at the ankle joint and draw free body diagram 9.Hip Joint Forces During Walking A person is walking, and their hip joint is flexed at a 30° angle. The weight of the lower limb is 15 kg, and its center of mass is 30 cm from the hip joint. The hip abductor muscles exert a force at a 60° angle to the vertical, with a moment arm of 5 cm. Calculate: - The joint reaction force at the hip joint. - The force exerted by the hip abductor muscles - Draw free body diagram. Need Assignment Help?
