Pendulum and Hydrostat Control — is a simple system for automatically controlling the depth in water of a machine. The hydrostat senses the depth, sometimes this initially was with a simple bellows. However, with only a Hydrostat the system would tend to oscillate around the… … Wikipedia
Pendulum (mathematics) — The mathematics of pendulums are in general quite complicated. Simplifying assumptions can be made, which in the case of a simple pendulum allows the equations of motion to be solved analytically for small angle oscillations. Simple gravity… … Wikipedia

Pendulum (derivations) — Derivations from Pendulum (mathematics). Analysis of a simple gravity pendulum To begin, we shall make three assumptions about the simple pendulum: * The rod/string/cable on which the bob is swinging is massless, does not stretch, and always… … Wikipedia

Conical pendulum — A conical pendulum is a weight (or bob) fixed on the end of a string (or rod) suspended from a pivot. Its construction is similar to an ordinary pendulum; however, instead of rocking back and forth, the bob of a conical pendulum moves at a… … Wikipedia
Inverted pendulum — An inverted pendulum is a pendulum which has its mass above its pivot point. It is often implemented with the pivot point mounted on a cart that can move horizontally and may be called a cart and pole. Whereas a normal pendulum is stable when… … Wikipedia
