Equilibrium of Non-Concurrent Force System 1. Weight lifter Hidilyn Diaz made a history becoming the first atlete from the Philippines to win gold at the Olympics. She competed in the women's 55 kg weightlifting competition during the Tokyo 2020 Olympic Games at the Tokyo International Forum in Tokyo on July 26, 2021. She lifted a barbell with the total weight of 127 kg comprising of weight of plates: W1 = 50 kg, W2 = 6 kg; and standard weight of the olympic bar, W3 = 15 kg where it is located at the centroid of the bar. The standard length of women's olympic bar is 2.01 meters. As long as she is holding the barbell above her head, both bodies (weighlifter and barbell) are in static equilibrium. What are the forces, R1 and R2 exerted by her arms to keep her in static equilibrium? Assume the olympic bar is rigid. 2 O10 mm 1420 mm W3 90mm 320 mm 320 n 65 68 R, R2 W, PHILIPPINES
