Pulley A.
Pulley B.
Pulley C.
Pulleys A, B, and C have the same mechanical advantage.
Based on the graph showing efficiency, it can be determined that the pulley with the highest mechanical advantage is Pulley A. This is because it has the highest efficiency out of the three pulleys, indicating that it requires the least amount of input force to lift the load. Therefore, Pulley A has the highest mechanical advantage.
You are working as a quality control engineer. You test four machines to determine their efficiency. The LEAST efficient machine needs to be sent in to a special shop to be repaired. Which of the following machines is most likely in need of a trip to the repair shop?
Efficiency=(Output Work/Input Work) x 100%
