Simple Machines

Key Questions

• What is a lever?

  A lever is a simple machine comprised of a long beam or rod that is fixed to a pivot point (fulcrum) onto which a load is attached and an effort force is applied.

  Levers work to reduce the amount of effort force required to move a load, providing a mechanical advantage. Longer levers provide a greater mechanical advantage.

  This very short video explains levers very well:
