Study Notes
Simple Machines
- A simple machine is a basic device that helps to modify the direction or magnitude of a force, making it easier to lift, move, or manipulate objects.
Defining Simple Machines
- Simple machines can be defined as devices that change the magnitude or direction of a force, allowing us to accomplish tasks with less effort.
The Six Classical Simple Machines
- The six classical simple machines are:
- Inclined plane
- Lever
- Wheel and axle
- Pulley
- Screw
- Wedge
Input and Output Forces
- In a simple machine, the input force is the effort applied to the machine, while the output force is the resulting force that is produced.
- The relationship between the input and output forces is that the output force is often greater than the input force, making it easier to accomplish tasks.
Mechanical Advantage
- The mechanical advantage of a simple machine is the ratio of the output force to the input force, which is often greater than one.
- A higher mechanical advantage means that less effort is required to produce a greater force, making it easier to accomplish tasks.
