Wind up Toywindup toy
It' call it saving power. Toys for winding consist of a feather which is fixed to a winding machine. Turning the coiler, the power used to turn the coiler is saved in the feather in the form o f potencial power. When the elevator is released, the feather tries to unfurl and the accumulated electrical power is transformed into physical power, which is then transmitted to the gear wheels fixed to the feather.
Something known as the Act of Preservation of Energy coarsely states that it is possible to convert power from one shape to another (with some losses of course). Wherever you turn the wrench when winding a toy, you supply power for the inner springs. These energies are saved in the shape of the feather's possible energies.
If you switch on the toy, this saved power is used for movement. Therefore, if the toy will stop, you must turn the keys again (supply energy) for it to work. P.S.:The concept of saving and saving power will probably be clarified in higher levels.... Normally the feather is in a pulled off postion, but when the wrench turns, it becomes firmer and firmer.
When fully coiled, the feather is full of potentially explosive force prepared to be unleashed to drive the toy. Bending at the end of the feather is hooked into a cog next to the bike to prevent the feather from rolling off immediately. Toy wrapping is based on the fundamental idea of "converting one type of engery into another".
Toy coiling uses either kinematic power or movement from the potentially generated power contained in the toy mechanism's springs or gears. Initially, the entire mechanics are centred on a single feather (main feather or coil spring). If you squeeze a feather, it tries to restore its initial form.
This means that the feather wants to come into a released or developed state. So, when we squeeze or wrap a feather (with a key), we actually (kx) work on it and this work is saved as "spring/potential energy" (i.e. it has the capacity to work) so that this power is then brought into mechanic (motion) shape with the help of the gear wheels.
It is a straightforward answer: it is a single motion combining a single sprung motion with a single leverage motion in which the elevator increases the stress on the springs. This is the part where the operation occurs, the feather is fixed to the various handles that connect the different parts of the toy, making it move or perform an operation until the stress in the feather decreases.
