MACHINES Devices that make work easier by changing the size and/or the direction of the force. They will not do work for you.
SIMPLE MACHINES Machines that can do a task with one single movement.
SIMPLE MACHINES Lever Pulley Wheel and Axle Inclined Plane Screw Wedge
Lever A simple machine consisting of a bar that is free to pivot (rotate) around a fixed point called the fulcrum. Ex: scissors, crowbar
Pulley A simple machine consisting of a grooved wheel with a rope running along the groove. Ex: flagpole
Wheel & Axle A simple machine consisting of two different sized wheels that rotate together. Ex: door knob, steering wheel
Inclined Plane A simple machine consisting of a sloping surface or ramp used to raise objects. Ex: loading ramp
Inclined Planes Mountain roads are inclined planes so that cars dont have to climb straight up. A definite advantage! Also, think about parking garages.
Screw A simple machine consisting of a special type of inclined plane wrapped in a spiral around a cylindrical post. Ex: spiral staircase, screw
Wedge A simple machine consisting of a moving inclined plane with one or two sloping sides. Ex: knife, chisel
Compound Machines A compound machine is a combination of several simple machines. Ex: bicycle
