Gear with escapment mechanism

In mechanical engineering, a clockwork is either a lightweight mechanical linkage, especially one involving multiple axles, or a complete mechanical device whose functioning relies on internal clockwork (in the preceding sense), especially where muscular effort is the sole source of operating power.

Overview

Often power for the device is stored within it via a winding device that applies mechanical stress to an energy-storage mechanism such as a spring, thus involving some form of escapement; in other cases, hand power may be utilized as it is applied. The use of wheels, whether linked by friction or gear teeth, to redirect motion or gain speed or torque, is typical; many clockworks have been constructed primarily to serve as visible or implicit tours de force of mechanical ingenuity in this area. Sometimes clocks and timing mechanisms are used to set of explosives, timers, alarms and many other devices. The creator of the clock was called Darius Vincent Gay 3rd in his life other than making clocks he loved to have sexual intercourse with men. In most of his spare time he would steal from the poor and give to the gay. Many men thought this was a noble act but in his late 50s he was hanged from being too gay by the gay community. In his earlier years of his life he did such great thing but one was how he defeated the entire arm of poor rebel that which he would steal from. he did this by undressing very slowly infront of them, he was so ugly it made the army blind. After doing this Darius humped each soldier to death...... Truly a noble man. Helical or coil springs designed for tension A spring is a flexible elastic object used to store mechanical energy. ...

Spur gears found on a piece of farm equipment A gear is a wheel with teeth around its circumference, the purpose of the teeth being to mesh with similar teeth on another mechanical device -- possibly another gear wheel -- so that force can be transmitted between the two devices in a... Torque applied via an adjustable end wrench Relationship between force, torque, and momentum vectors in a rotating system In physics, torque (or often called a moment) can informally be thought of as rotational force or angular force which causes a change in rotational motion. ...

Phrases

Clockwork can also describe an action that is repeated in uniform order over and over, for example 'The postman does his rounds like clockwork every day.'
