Study Notes
Types of Simple Machines
- Lever, pulley, and wheel and axle are examples of simple machines.
Purpose of Simple Machines
- The primary purpose of a simple machine is to make work easier by reducing the amount of effort required to accomplish a task.
Screw as a Simple Machine
- A screw is an example of an inclined plane type of simple machine.
Levers
- The primary purpose of a lever is to provide a mechanical advantage to lift or move heavy loads.
- In a compound lever, the effort is applied between the pivot and the load.
Wheel and Axle
- The primary purpose of a wheel and axle is to reduce friction and make it easier to move objects.
Inclined Plane
- An inclined plane is a simple machine that consists of a sloped surface used to reduce the amount of effort required to lift an object.
- A first-class lever is used to decrease the amount of force required to lift the load.
Levers and Pivots
- A lever consists of a rigid bar that rotates around a fixed point called a pivot.
Wedge
- The primary purpose of a wedge as a simple machine is to split, lift, or separate objects.
Pulley
- A pulley is a simple machine that consists of a grooved wheel used to change the direction of a pulling force.
Main Purpose of Simple Machines
- The main purpose of a simple machine is to make work easier by providing a mechanical advantage to lift or move heavy loads.
Functions of Simple Machines
- Simple machines are designed to amplify force, increase speed, or transmit motion from one place to another.
