Question
Rohan exerts a pull of 150 kgf. What is the maximum load he can raise with thispulley system if its efficiency = 75%
Solution
To solve this problem, we first need to understand that the efficiency of a pulley system is the ratio of the output force to the input force.
Step 1: Convert the efficiency percentage to a decimal. 75% = 0.75
Step 2: Calculate the maximum load Rohan can raise with the pulley system. The formula to calculate the maximum load (output force) is:
Output Force = Input Force x Efficiency
So,
Output Force = 150 kgf x 0.75 = 112.5 kgf
Therefore, the maximum load Rohan can raise with this pulley system is 112.5 kgf.
