Pulley Efficiency Formula
The following formula is used to calculate the Pulley Efficiency.
Epull = WL / AF * 100
- Where Epull is the Pulley Efficiency (%)
- AF is the total force applied to pulley (N)
- WL is the weight lifted by pulley (N)
How to Calculate Pulley Efficiency?
The following two example problems outline how to calculate the Pulley Efficiency.
Example Problem #1:
- First, determine the total force applied to pulley (N). In this example, the total force applied to pulley (N) is given as 20.
- Next, determine the weight lifted by pulley (N). For this problem, the weight lifted by pulley (N) is given as 30.
- Finally, calculate the Pulley Efficiency using the equation above:
Epull = WL / AF * 100
Inserting the values from above and solving the equation:
Epull = 30 / 20 * 100 = 150 (%)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are:
total force applied to pulley (N) = 50
weight lifted by pulley (N) = 100
Entering these values yields:
Epull = 100 / 50 * 100 = 200 (%)
