The efficiency of a pulley system can be increased by reducing the friction on the pulleys. Reducing friction allows more of the input energy to be used effectively for lifting the load, thereby increasing the overall efficiency of the system.
A pulley system is operating at only 50% efficiency. How could the efficiency be increased? (1 point)
