![]() Lever What is it? A lever is a plank or bar that pivots on a fulcrum. Levers provide a mechanical advantage when lifting or prying. Give me an example! Have you ever played on a seesaw? The board you sit on acts as a lever that pivots on a central fulcrum as you ride up and down. Copyright ©2010, PCS Edventures, Inc. All Rights Reserved. |
