Mechanical Advantage
Makes Work Easier
Everyday Machines
100
used to move things to a higher location
What is an inclined plane?
100
In this lever, the fulcrum is in the middle between the effort force and the load
What is a first class lever?
100
this will increase the mechanical advantage of an inclined plane
What is make the ramp longer?
100
changes the direction of force to split or push things apart
What is how a wedge makes work easier?
100
scissors are this type of lever
What is first class lever?
200
used to split things apart or separate things
What is a wedge?
200
In this lever, the effort force is in the middle of the load and the fulcrum
What is a third class lever?
200
this will increase the mechanical advantage of a wedge
What is make the point thinner/sharper or make the blade longer?
200
changes the direction of the applied force (example-twist, tighten as force goes down)
What is how the screw makes work easier?

the simple machines that make up a wheelbarrow
What are second class lever, inclined plane, and wheel and axle?
300
used to hold things together
What is a screw?
300
In this lever, the load is in the middle of the effort force and the fulcrum
What is a second class lever?
300
this will increase the mechanical advantage of a screw
What is move the threads closer together?

used to move things from one place to another
What is a wheel and axle?
400
the pivot point
What is the fulcrum?
400
this will increase the mechanical advantage of a wheel and axle
What is make the wheel bigger or add more wheels?
400
reduces the effort force needed to raise an object along a plane
What is how an inclined plane makes work easier?
400

used to raise things up to a higher elevation
What is a pulley?
500
this will increase the mechanical advantage of a lever
What is move the fulcrum or make the lever longer ?
500
this will increase the mechanical advantage of a pulley
What is add more pulleys?
500
changes the direction of force (example-easier to pull down than lift)
What is how a pulley makes work easier?
