Apulley system is used to lift a 2,000 newton engine up a distance of 3 meters. the operator must apply a force of 250 newtons to the chain of the pulley system to lift the motor. to lift the engine 3 meters, the operator must pull a total of 30 meters of chain through the pulley system. what is the value of do?

The efficiency of the system is 80%.

Explanation:

Given that,

Output force = 2000 N

Distance = 3 m

Input force = 250 N

Distance = 30 m

Suppose we need to find the efficiency of the system

We need to calculate the efficiency of the system

Using formula of efficiency

Put the value into the formula

Hence, The efficiency of the system is 80%.
