Answer:
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%.
