Slide1
Transmission and transformation of motion
Carry the motion over a distance
And
Change the type of motionSlide2
Transmission of motion
A group of simple machines can work together to make a
system
.A system can transmit or carry the motion from one object to another.Sometimes they are close together.Sometimes they are far away.Slide3
Here are the different systems
Chain and sprocket
Just like on your bicycle
Your feet turn and move the big sprocket then the chain carries the circular
motion to the little sprocket on the back wheel and makes the bike goSlide4
Belt and pulley
You pull on the rope and it carries the motion to bring in the clothes.
Both pulleys turn in the same
Direction. The clothes move in a straight lineSlide5
gears
Gears are toothed wheels
They can transmit the motion and change it’s direction.
Like an egg beater or a clockSlide6
Friction wheels
Are a lot like gears but with no teeth
They turn in opposite directions.
One wheel turns the other because of the friction where they touchSlide7
Pulley systems
These systems transmit rectilinear motion.
You pull one rope and it goes through the pulleys and lifts a heavy object in a linear direction.Slide8
Now
answer the memory questions on p 422Slide9
Types of motion
There are 4 kinds of motion:
Rectilinear
AlternationCircular
OscillatorySlide10
Transformation of motion
Is when you can change 1 kind of motion into another.
You pin wheel changes circular motion in to linear motionSlide11
Here are some other systems that do that
Rod and crank changes circular motion into alternation motion to
Drive your car or a trainSlide12
Cam and follower
Changes circular motion into alternating
motion
the egg shaped cam is close to the rod then far from the rod as it turnsSlide13
Rack and pinion
Changes circular motion to rectilinear motion
You turn the focus knob and the lenses go up and down on the microscope.Slide14
Screw and nut
This changes circular into rectilinear motion.
It can be used to lift you ceiling
or squeeze or even change a tire.Slide15
Now
