What This Calculator Does
Estimate mechanical advantage and effort for a pulley system.
It combines Load, Number of Pulleys to estimate Mechanical Advantage, Required Effort.
Formula & Method
In this idealized model, mechanical advantage equals pulley count: MA=n and required effort is F_e=\frac{Load}{MA}.
Notation used in the formulas: R = Mechanical Advantage; x_{1} = Load; x_{2} = Number of Pulleys.
Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.
Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.
Inputs Used
- Load: Used directly in the calculation.
- Number of Pulleys: Used directly in the calculation.
