I believe a bridge should be considered a simple machine. It saves work and gives mechanical advantage. It can also shorten distance, so unlike an inclined plane it can benefit without increasing distance. It can bypass the need to raise and lower massess into crevasses, it can bypass long journeys down then back up a hill. I could find no discussion anywhere.
A complex machine.
A train is not a simple machine.
A fulcrum is a part of a simple machine, the lever. Without the fulcrum what is left of the simple machine can no longer increase the applied force and is no longer a simple machine.
yes a door knod is a simple machine
A spade is a simple mechanical (tool) machine.
An airplane is not a simple machine. A lever is a simple machine. A wheel is a simple machine. Any machine that can be described by a mathematical formula is a simple machine.
