QUESTION 7: (10 marks) i- Fig. shows a single-segment coplanar analysis at knee of lower leg flexion motion. Describe a dynamic biomechanical model illustrating all possible forces and moments acting on the knee. ii- If the mass of the lower leg and foot is 3.7 kg, the mass center r is 230 mm, and the radius of gyration is 140 mm, draw the kinematic relations for typical high-speed forearm flexion with the range of angle 0 from (0 to 170°) in the interval of 0.2 s.
