Description

How does paddling move a boat forward? Why does a wheelbarrow have only one wheel? What does a counterweight do? Levers are simple machines that can be used to make other machines work. When you used a shovel, play on a seesaw, or use a bottle opener you are using lever. Levers explains what levers are and how they help you do everyday things. - from Amzon
