How it makes work easier: Helps lift things up and down or move them across
Examples: Flagpole, clothesline, tow truck, crane
Definition – A stiff bar that rests on a support called a fulcrum. It pivots (turns) against the fulcrum. There are 3 types, and the type is determined by where the fulcrum is. The types are 1st class, 2nd class, and 3rd class.
How it makes work easier: It lifts and moves loads.
Examples: seesaw, scissors, crowbar
Examples: wheelbarrow, nutcracker
Examples: broom, shovel, bat
