Simple Machines

6. – A rigid bar that pivots around a fixed point to move a load.
8. – The object or weight being moved by the machine.
9. – Two inclined planes joined together, used to split, cut, or push objects apart.
10. and axle – A large wheel attached to a smaller rod (axle) that turn together to make moving objects easier.
12. – The force you apply to make a machine work.
14. machine – A basic device that makes work easier by changing the size or direction of a force.
18. lever – A lever in which the load is between the fulcrum and the effort.

1. pulley (block and tackle) – A system that combines fixed and movable pulleys to increase mechanical advantage.
2. plane – A flat surface set at an angle to help lift heavy objects with less force.
3. pulley – A pulley attached to the load that reduces the effort needed to lift it.
4. – An inclined plane wrapped around a cylinder, used to hold objects together or lift materials.
5. – A grooved wheel with a rope or chain used to lift heavy objects.
7. – A push or pull acting on an object.
10. – When a force moves an object over a distance (W = F × d).
11. lever – A lever in which the effort is between the fulcrum and the load.
13. lever – A lever in which the fulcrum is between the effort and the load.
15. pulley – A pulley attached in one place that changes the direction of the force.
16. – The length over which an object moves.
17. - The fixed point on which a lever turns.
