Study Notes
Machine Types
- A machine that does not provide energy by itself or transform energy from one form to another is a mechanical device.
Mechanical Advantage of a Lever
- The mechanical advantage of a lever is the ratio of the output force to the input force, which allows for a gain in force or distance.
Complex Machines
- An example of a complex machine is a bicycle, which combines multiple simple machines to achieve a specific task.
Function of Machines
- Machines make our work easier and faster by applying force, changing direction, or gaining distance.
Computer and Telephone Classification
- Computers and telephones are examples of machines that use electrical energy to perform specific tasks.
Function of Simple Machines
- The function of a simple machine is to change the direction or magnitude of a force, making it easier to perform a task.
External Force
- The term "effort" refers to the external force applied to a machine, which is used to achieve a specific task.
Fulcrum Function
- The function of a fulcrum in a machine is to provide a pivot point, allowing the force to be applied at a specific point.
Velocity Ratio
- The Velocity Ratio (VR) represents the ratio of the output velocity to the input velocity in the study of simple machines.
Mechanical Advantage Measurement
- Mechanical Advantage (MA) measures the ratio of the output force to the input force in a machine, which determines its efficiency.
