You are assessing the shoulder joint kinetics in order to design an artificial joint. Answer the questions (a)-(d). FAI W D Wc Point coordinates (cm): A(10,5); B(10,2); C(6,0); D(12,-10) Bone mass (kg): 2 kg at C; 0.5 kg at D Magnitude of muscle force (N): F = 7; Fe = 15 (a) Compute the mass center utilizing the given bone mass and point coordinates Answer: (b) Compute the net force (resultant) (in vector format) combining muscle forces and weight. Use 9.81 m/s for a gravitational acceleration. (c) What is the net moment with respect to the body center O? Answer: (d) What is the net moment with respect to the shoulder joint B?
