made up of two circular objects that rotate together
What is wheel and axle
100
longer the incline, more distance but less
What is work
100
an inclined plane that moves
What is wedge
200
resistance in middle (F-R-E)
always multiply effort force
does not change direction of effort force
input length is greater than output
ex. wheel barrow
What is 2nd class lever
200
a rope, belt, or chain wrapped around a wheel
What is lever
200
effort force(where you do work)
What is wheel
200
increases effort distance, decreasing...
What is effort force
200
closer the threads...
What is easier to turn
300
fulcrum in middle (R-F-E)
can be used to multiply effort force
can be used to increase the distance
changes direction of force
ex. seasaw
What is 1st class lever
300
can multiply the effort force
What is movable pulley
300
radius of wheel/ radius of axle
What is ima of wheel and axle
300
ima of an inclined plane
What is length of slope/ height of slope
300
an inclined place wrapped around a cylindrical post
What is screw
400
effort force is in the middle (R-E-F)
does not multiply effort force
increases distance and speed
ex. hockey stick
What is 3rd class lever
400
number of rope sections not counting the section that you pull down
