125:201 Introduction to Biomedical Engineering Biomechanics, Homework #2 Due Monday October 24 th Problem 1 A) Find the joint reaction force, R, and the abductor muscle force, M, in the right hip when a woman stands on her right leg while carrying a 25kg suitcase in the left hand (Fig 7.7A). You can use the following data: Body weight = 600N Weight of standing leg = 100N Moment arm of the weight of the suitcase = 0.31m Moment arm of the abductor muscle force = 0.05m Moment arm of the body weight = 0.05m Moment arm of the body weight excluding the standing leg = 0.06m Moment arm of the standing leg = 0.01m (medial to the joint) Moment arm of the ground reaction force = 0.06m (medial to the joint) Abductor muscle force (M) acts at a 70 degree angle to the transverse plane. (The moment arm is defined as the perpendicular distance from a force) B) Find R and M for the right hip joint when the woman stands on the right leg while carrying a 25kg suitcase in each hand (Fig 7.7b). The moment arm for the weight of the
