becuz it not electronic and it is easy to use .

It's a screw on thanks!
A wrench and a pipe are types of levers, which are simple machines. A wrench operates as a lever to amplify force when turning a bolt or nut, while a pipe can be used as a lever arm to provide additional torque when loosening or tightening fittings. Both tools leverage mechanical advantage to make tasks easier.
A complex machine.
A train is not a simple machine.
A wrench is a wheel because when put over a bolt it spins like a wheel. The bolt would be the axle. A wrench is a wheel and axle simple machine.

Not a machine but a tool, a wrench.

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.
It is a simple lever mechanism using to hold round objects firmly without slipping, as well as to tighten square, hexagonal nuts or bolts.
A hook isn't really a "machine" at all. Depending on its construction, in a particular application it might be operating as a lever, or possibly as an inclined plane, but it's really not possible to say with any certainty what kind of simple machine it is without more details of exactly what the hook is doing. It may not be any kind of simple machine.
A seesaw is a simple machine that has a continuous lever with equal arms. When one end of the seesaw is pushed down, the other end goes up, demonstrating the principle of a lever with balanced arms.
