LeverExamples of machines using
lever: bottle opener, nutcracker, fishing rod, fan,
scissors and shovel.
Wheel and AxleExamples of machines with wheel
and axle: car, bicycle, office chair, shopping cart, roller
skates
Inclined plane
Examples of inclined plane: ramps and stairs
Wedge
Examples of machines with wedges: axe, doorstop,
saw, zipper, scissors, knife, fork, bow of a boat
Screw
Examples of machines with screws: screws, bolts, clamps, jar lids,
spinning stools, spiral staircases
PulleyExamples of machines with
pulleys: flag pole, sails, cranes, window shades and
blinds
Simple Machines make work easier
Types of simple machine include:- lever- wheel and axle- inclined plane- wedge- screw- pulley
Compound machinesSimple machines connected to
each other to work together
Compound machinesSimple machines connected to
