-IMA:force is applied divided by the length of the lever are that lifts the load

-real-life example:seesaw

-how does it work?:the force you push on it the more it raises

-IMA:the ratio of the circumference of the screw to the distance it advances during each revolution

-real-life example:screw

-how does it work?:you screw in a screw to hold things together

-IMA:directly dependent upon the number of support strings, N.

-real-life example:crane

-how does it work?:you pull a rope and it raises something that is hard to lift normally

-IMA: has none

-real-life example:axe

-how does it work?:it lifts things of the ground like a ramp

-IMA:(IMA) of a wheel and axle is the ratio of the radii

-real-life example:steering wheel

-how does it work?:like a steering wheel you can turn it and it then changes the way it moves

-IMA:length of the incline divided by the vertical rise, the so-called run-to-rise ratio

-real-life example:slide

-how does it work?:it allow things to easily move up things they can't
