Calculate Mechanical Advantage (MA)



Formula

The formula to calculate the Mechanical Advantage (MA) is:

\[ \text{MA} = \frac{\text{ea}}{\text{la}} \]

What is Mechanical Advantage?

Mechanical advantage is a term used to describe the ratio of an output force to the input force. In other words, it measures how much a machine amplifies an input force. Using physics and leverages, certain mechanical features can be constructed to output a larger force than was input. In the case of a lever, the mechanical advantage is directly related to the length of each arm. Each arm has an equal effect on the mechanical advantage.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Mechanical Advantage:

\[ \text{MA} = \frac{4}{2} = 2 \]

The Mechanical Advantage is 2.
