An athlete exercises his arm by raising the 8-kg mass m. The shoulder joint A is stationary. The distance AB is 300 mm the distance BC is 400 mm, and the distance from C to the pulley is 340 mm. The angular velocities ωAB = 1.5 rad/s and ωBC = 2 rad/s are constant. What is the tension in the cable?
