A Simple Machine Calculator is a tool used to calculate the mechanical advantage, efficiency, force, distance, and other properties of simple machines — like levers, pulleys, inclined planes, wedges, screws, and wheel-and-axle systems. These are the basic devices that change the direction or magnitude of a force and form the foundation for more complex machinery.

Why use a Simple Machine Calculator?

  • Educational purposes: Helps students learn about physics and mechanics.
  • Engineering and design: Assists in designing machines with proper force and motion ratios.
  • Practical problem-solving: Calculates effort needed to lift or move objects efficiently.

How does it work?
You input values like force, distance, or angle, and the calculator applies formulas for mechanical advantage and work output. For example:

When is it used?

  • In physics labs and classrooms
  • During mechanical design and prototyping
  • In real-life scenarios involving lifting or moving heavy objects efficiently
