Final answer:
The ideal Mechanical Advantage of the pulley system is approximately 4, which means four ropes are required to lift the load, making the correct answer "d. 4 ropes are required because the actual mechanical advantage is 3.80". The correct answer is c) 5:1.
Step-by-step explanation:
The ideal Mechanical Advantage (MA) of a pulley system is found by counting the number of ropes supporting the load. If a pulley system can lift a 200N load with an effort force of 52 N and has an efficiency of almost 100 percent, we can calculate the ideal mechanical advantage (IMA) as the ratio of the load force to the effort force, which is 200 N / 52 N = 3.85 (approximately 4).
Since the real pulleys are nearly 100% efficient in this scenario, the ideal mechanical advantage and actual mechanical advantage are about the same. Therefore, the correct answer to the question is d. 4 ropes are required because the actual mechanical advantage is 3.80.
This assumes that the number of supporting ropes equals the mechanical advantage, which is the case in a frictionless system according to the provided information.
The ideal Mechanical Advantage (MA) of a pulley system can be determined by counting the number of ropes supporting the load.
In the given pulley configuration, there are four ropes attached to the load. Therefore, the ideal MA of the system is 4:1.
