An hourglass is not classified as a simple machine. Simple machines, such as levers, pulleys, and inclined planes, are devices that change the direction or magnitude of a force to perform work. An hourglass primarily functions as a timekeeping device using the flow of sand, rather than performing mechanical work in the sense defined by simple machines.
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.
No, a lever is a simple machine that makes life easier. An hourglass is a glass container tapered in the center with sand in the bottom, and is used to tell time. They are not the same thing.
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.
A pulley isn't a kind of simple machine, it is a simple machine
