How do you explain a lever to a child?

What are the parts of a lever?

There are four parts to a lever – lever arm, pivot, effort and load.

What are simple levers?

A lever is a simple machine made of a rigid beam and a fulcrum. The fulcrum is the point on which the beam pivots. When an effort is applied to one end of the lever, a load is applied at the other end of the lever. This will move a mass upward. Levers rely on torque for their operation.

What is a class 1 lever examples?

Other examples of first class levers are pliers, scissors, a crow bar, a claw hammer, a see-saw and a weighing balance. In summary, in a first class lever the effort (force) moves over a large distance to move the load a smaller distance, and the fulcrum is between the effort (force) and the load.

What are fun facts about levers?

Fun Facts

• The longer the lever, the higher you can lift an object.
• In a type 1 lever, the fulcrum (pivot) is between the object to be moved and the effort.
• A see-saw is a very simple type 1 lever.
• In a type 2 lever, the load is between the fulcrum and the effort.
