A simple machine is a basic mechanical device that changes the direction or magnitude of a force. Common examples include the lever, pulley, inclined plane, wedge, screw, and wheel and axle. These machines help to make work easier by allowing users to exert less effort to accomplish tasks.
A lever
wheel and axle
This is called a pulley.
Bicycle
compound machine
The force applied to a simple machine is called effort/input force.
a pulley is called a moving simple machine because it moves
A compound machine.
When simple machines work together, that forms a compound machine.
The fixed turning point of a simple machine is called the fulcrum. The fulcrum is the point around which the machine rotates or pivots to perform work.
simple machine such as pulleys and levers make work easier
the work a machine does is the work output what it takes to do the work is the work input
When two or more simple machines work together, they are called a compound machine. Compound machines are systems that combine multiple simple machines to perform more complex tasks or amplify force.
A lever
The force that a simple machine applies is called effort force. It is the force that is applied to operate the machine and overcome resistance.
It is called a machine.
The force to be overcome by a simple machine is called the input force or effort force. This is the force applied to the machine in order to make it work against the resistance force or load.
