Mechanical Advantage Table
The following table summarizes the different types of mechanical advantage:
| Type of Mechanical Advantage | Formula | Example |
|---|---|---|
| Ideal Mechanical Advantage | IMA = Output Force / Input Force | A lever with a fulcrum located at one end has an IMA of 2. |
| Actual Mechanical Advantage | AMA = Output Force / Input Force | A lever with a fulcrum located at the center has an AMA of 1. |
| Velocity Ratio | VR = Output Velocity / Input Velocity | A gear with a ratio of 2:1 has a VR of 2. |
Mechanical Advantage Diagrams
The following diagrams illustrate the different types of mechanical advantage:
- Lever: A lever is a simple machine that consists of a rigid bar that pivots on a fixed point called a fulcrum. The input force is applied to one end of the lever, and the output force is applied to the other end.
- Pulley: A pulley is a simple machine that consists of a wheel and a rope. The input force is applied to the rope, and the output force is applied to the wheel.
- Gear: A gear is a simple machine that consists of two or more toothed wheels that mesh together. The input force is applied to one gear, and the output force is applied to the other gear.
