A lever
This is called a pulley.
Bicycle
wheel and axle
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.
simple machine such as pulleys and levers make work easier
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.
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
It is called a machine.
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.
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.
