  2. Damping - Wikipedia

    en.wikipedia.org/wiki/Damping

    The damping ratio is a system parameter, denoted by ζ ("zeta"), that can vary from undamped (ζ = 0), underdamped (ζ < 1) through critically damped (ζ = 1) to overdamped (ζ > 1). The behaviour of oscillating systems is often of interest in a diverse range of disciplines that include control engineering , chemical engineering , mechanical ...

  3. Front (physics) - Wikipedia

    en.wikipedia.org/wiki/Front_(physics)

    In physics, a front [1] [2] can be understood as an interface between two different possible states (either stable or unstable) in a physical system. For example, a weather front is the interface between two different density masses of air, in combustion where the flame is the interface between burned and unburned material or in population dynamics where the front is the interface between ...

    the small front sprocket on a chain driven motorcycle. the clutch bell gear when paired with a centrifugal clutch , in radio-controlled cars with an engine (e.g., nitro ). [ 2 ]

  5. Harmonic oscillator - Wikipedia

    en.wikipedia.org/wiki/Harmonic_oscillator

    A simple harmonic oscillator is an oscillator that is neither driven nor damped.It consists of a mass m, which experiences a single force F, which pulls the mass in the direction of the point x = 0 and depends only on the position x of the mass and a constant k.

  6. Sprocket - Wikipedia

    en.wikipedia.org/wiki/Sprocket

    The sprocket wheels a, b, and c engage and transport the film. a and b move with uniform velocity and c indexes each frame of the film into place for projection. Sprockets are used in the film transport mechanisms of movie projectors and movie cameras. [5] In this case, the sprocket wheels engage film perforations in the film stock.

  7. Continuous track - Wikipedia

    en.wikipedia.org/wiki/Continuous_track

    Continuous track or tracked treads are a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tyres on an equivalent vehicle, enabling continuous tracked ...

  8. Mechanics - Wikipedia

    en.wikipedia.org/wiki/Mechanics

    Mechanics (from Ancient Greek μηχανική (mēkhanikḗ) 'of machines') [1] [2] is the area of physics concerned with the relationships between force, matter, and motion among physical objects. [3]

  9. Rack and pinion - Wikipedia

    en.wikipedia.org/wiki/Rack_and_pinion

    A rack and pinion has roughly the same purpose as a worm gear with a rack replacing the gear, in that both convert torque to linear force. However the rack and pinion generally provides higher linear speed — since a full turn of the pinion displaces the rack by an amount equal to the pinion's pitch circle whereas a full rotation of the worm screw only displaces the rack by one tooth width.
