Simple Machine Aries Triwidajati S. SPd
To understand motion, work, force and energy concepts in daily life
Do the experiment with simple machine and their application in daily life
Students are able to : 2. Show the using of simple machine tools
in daily life such as: lever, wedge, inclined plain, etc.
Key Words 2. 3. 4. 5. 6. 7. 8. 9. 10.
lever wheel and axle inclined plane wedge screw Pulley Effort Fulcrum Resistance
Simple Machine
Simple Machine Simple
machines are simple tools used to make work easier
Machines
change the size or direction of the applied force.
6 simple machines are: 1. 2. 3. 4. 5. 6.
lever wheel and axle inclined plane wedge screw pulley
Levers The
resistance and effort move about the fulcrum.
Levers: 3 types
First class lever Fulcrum
is between effort and: resistance
Example : hammer
2nd Class Levers The resistance is located between the effort force and the fulcrum.
Example : corkscrew
3rd Class Levers The effort force is located between the resistance force and the fulcrum.
Example : fishing rod
Wheel and Axle is a lever rotating in a circle
Examples of Wheel and axle are
Inclined
Plane: any sloping surface used to raise objects, such as a ramp
Examples of inclined plane are
Wedge is an inclined plane that moves.
SCREW is an inclined plane wrapped around a cylinder to form a spiral A screw multiplies effort by acting through a long effort distance.
PULLEY is this variation of the wheel and axle
