Meaning and Definition
A basic mechanical device that applies a force to change the direction or magnitude of a force.
One of the six fundamental devices (lever, pulley, wheel and axle, inclined plane, wedge, screw) from which all more complex machines are composed; often used as an educational concept in physics to explain mechanical advantage.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Both use the same term. Spelling of related words may differ (e.g., 'mechanise' vs. 'mechanize').
Connotations
Neutral, technical term in both. Slightly more common in US primary/elementary school science curricula.
Frequency
Low frequency in general discourse, moderate frequency in educational and introductory technical contexts. Roughly equal frequency in UK/US in these domains.

FAQ
Frequently Asked Questions
No, a bicycle is a compound machine because it combines several simple machines, such as wheels and axles, levers (brakes), and sometimes screws.
The 'six simple machines' is a classical categorization from Renaissance scientists that effectively describes all basic mechanical means of transferring force. Modern physics might describe them differently, but the classification remains a useful educational tool.
In formal writing, it's typically a compound noun. However, in technical descriptions, it can function attributively (e.g., 'simple machine principles'). It is not a standard adjective like 'simple'.
The primary purpose is to provide mechanical advantage, meaning it makes a task easier by changing the magnitude or direction of a force, though it does not reduce the total amount of work required.
Simple machine is usually technical/educational in register.
