Six Simple Machines

Question 1

What are the six simple machines

Answer 1

1. level
2. wheel and axel
3. pulley
4. inclined plane
5. wedge
6. screw

Question 2

What is the purpose of the 6 simple machines?

Answer 2

they reduce required effort by minimizing FRICTION or spreading effort over greater distance and time (most of our machines today, no matter how complex, are comprised of simple machines; which have existed for over thousands of years.)

Question 3

How do use an Incline Plane?

Answer 3

Think of it like a ramp, like up to a truck or plane

Question 4

What is the purpose of a wheel and axle?

Answer 4

reduces friction between truck and ground.

Question 5

What is the purpose of a lever?

Answer 5

You have a crow bar trying to pry two things apart. the further you are from the Fulcrum, you exert more mechanical advantage (The Fulcrum is the triangle thing holding it up.)

Question 6

What is a pulley?

Answer 6

Similar to wheel and axel, wrap a wheel or cord around it.

Question 7

What does the wedge do?

Answer 7

drive the metal wedge into the object, splitting it apart.

Question 8

What is a screw? ;)

Answer 8

as you spin the screw, it pulls the screw down and the wood up, wrapped around the axel.
