1) Figure A shows Free-body diagram of the right leg for someone standing on one leg, showing the forces and relevant dimensions. Find the magnitude of the muscle force M and the joint reaction force R? (3 points) -mass of the person is mp-100 Kg -N is the ground reaction force. - Wleg is the weight of the leg. -g-10 m/s2 2) When the same person in (1) holds a cane with his left arm, the right leg position changed as shown in the figure B below. Recalculate M and R? (the cane hold 2\5 of the boy weight(Wb)) (3 points) 3) Name Four antagonist muscles to the muscle M? (2 points)? M 4 70° 0.05 cm R 70° 6.98 cm 4.70 cm -7.0 cm; 17.8 cm 10.2 cm Figure A D 6.65 cm c.g. 11.7 cm-16.1 cm 17.8 cm Figure B
