What is a machine? A machine is a device that makes work easier by changing the amount of force you exert, the distance over which you exert your force,

Simple Machines!. Simple Machines Make work use less force by increasing the distance –When effort distance increases, effort force decreases! Six different.

Levers A lever is a rigid bar that pivots (rotates) about a fixed point. Levers are used to change the magnitude, direction, or speed of forces that act.

Moments A moment of a force is a measure of its tendency to cause a body to rotate about a point or axis. It is the same as torque. A moment (M) is calculated.

WHAT IS THIS THING THAT WE FIND IN PLAYGROUNDS?

Balance Those Masses!

Only a small effort is required to lift/move a heavier load. However, the smaller the effort, the further the distance required from the fulcrum.

LET’S LEARN ABOUT LEVERS

The EFFORT is the force that is used to move the lever. The LOAD is the object to be moved. The FULCRUM is the point at which the lever pivots. LOAD EFFORT FULCRUM

THE THREE CLASSES OF LEVERS

First Class Lever EFFORT LOAD FULCRUM The FULCRUM is between the load and effort. EFFORT LOAD FULCRUM

Second Class Lever EFFORT LOAD FULCRUM The LOAD is between the fulcrum and effort. EFFORT LOAD FULCRUM

Third Class Lever EFFORT LOAD FULCRUM The EFFORT is between the load and fulcrum. EFFORT LOAD FULCRUM
