Mechanical Adv Calc

How to Use Mechanical Adv Calculator?

A Mechanical Advantage Calculator helps you determine how effectively a machine amplifies the force you apply. You'll need to input two key details: the effort force you use and the load force the machine supports. By entering these values, the calculator will give you a mechanical advantage, which tells you how much the machine multiplies your effort.

1. Locate the Calculator: Open the Mechanical Advantage Calculator tool on your device.
2. Enter Effort Force: In the input field labeled "Effort Force(FE)," enter the amount of force you are applying to the machine. The force is measured in unit Newtons (N).
3. Enter Load Force: In the input field labeled "Load Force(FL)," enter the force the machine supports or lifts. This should also be measured in the same units as the effort force.

Once you have entered both values, click the “Calculate” button to determine the mechanical advantage.

Example;

Let’s say you use a pulley system to lift a heavy box. You apply a force of 20 Newtons to the pulley, and the pulley system can lift a load of 80 Newtons. You want to calculate the mechanical advantage of the pulley system to understand how effectively it amplifies your effort.

Effort Force(FE): 20 Newton

Load Force(FL): 80 Newton

Solution

Step 01: In the "Effort Force" field, input 20 Newtons (N).

Step 02: In the "Load Force" field, input 80 Newtons (N).

Calculate Mechanical Advantage: Click the “Calculate” button. The calculator processes your inputs and provides the mechanical advantage.

Formula:

Mechanical Advantage = Load ForceEffort Force

Mechanical Advantage = 80 N20 N = 4

Result

The mechanical advantage is 4. This means the pulley system amplifies your effort by a factor of 4. For every 20 Newtons you apply, the system can lift a load of 80.
