What is the formula to find the mechanical advantage (MA) of sheaves?

The formula to find the mechanical advantage (MA) of sheaves is based on the relationship between the diameters of the driven and drive sheaves. When using this formula, the mechanical advantage is determined by the ratio of the driven diameter to the drive diameter.

This ratio illustrates how the size difference between the two sheaves affects the force output. A larger driven diameter means that for every turn of the drive sheave, the driven sheave moves a greater distance, allowing for a multiplication of force applied to the load. Essentially, it shows how efficiently the system converts effort into useful work.

When considering this, it enhances understanding of mechanical systems where pulleys or sheaves are involved, as it allows for a clear calculation of how much easier a load can be lifted compared to the effort applied. Other options present different concepts not specifically relevant to mechanical advantage in the context of sheaves.
