Solved: The force F in Fig. 12-68 keeps the 6.40 kg block
Chapter , Problem 61(choose chapter or problem)
The force F in Fig. 12-68 keeps the 6.40 kg block and the pulleys in equilibrium. The pulleys x / Fig. 12-66 59. have negligible mass and friction. Fig. 12-67 60. Calculate the tension T in the upper cable. (Hint: When a cable wraps halfway around a pulley as here, the magnitude of its net force on the pulley is twice the tension in the cable.)
