    The turning rotation of a vessel about its vertical/Z axis. An offset or deviation from normal on this axis is referred to as deviation or set. This is referred to as the heading of the boat relative to a magnetic compass (or true heading if referenced to the true north pole); it also affects the bearing.

  3. Balancing of rotating masses - Wikipedia

    en.wikipedia.org/wiki/Balancing_of_rotating_masses

    These four readings are sufficient to define the size and position of a final mass to achieve good balance. Ref 4 For production balancing, the phase of dynamic vibration is observed with its amplitude. This allows one-shot dynamic balance to be achieved with a single spin, by adding a mass of internally calculated size in a calculated position.

  4. Limits of stability - Wikipedia

    en.wikipedia.org/wiki/Limits_of_stability

    In simpler terms, LoS represents the maximum distance an individual can intentionally sway in any direction without losing balance or needing to take a step. [2] The typical range of stable swaying is approximately 12.5° in the front-back (antero-posterior) direction and 16° in the side-to-side (medio-lateral) direction. [3]

    If a weight is used, then it rests upon the shoulders, or is held in the hand(s). This is an isolation exercise for the calves; it particularly emphasises the gastrocnemius muscle, and recruits the soleus muscle. [6] Equipment Body weight, dumbbells, barbell, Smith machine or standing calf raise machine. Major variants

  7. Torsion bar suspension - Wikipedia

    en.wikipedia.org/wiki/Torsion_bar_suspension

    A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a ...

  8. Torsion spring - Wikipedia

    en.wikipedia.org/wiki/Torsion_spring

    The sway bar used in many vehicle suspension systems also uses the torsion spring principle. The torsion pendulum used in torsion pendulum clocks is a wheel-shaped weight suspended from its center by a wire torsion spring. The weight rotates about the axis of the spring, twisting it, instead of swinging like an ordinary pendulum. The force of ...

  9. Spring scale - Wikipedia

    en.wikipedia.org/wiki/Spring_scale

    A spring scale, spring balance or newton meter is a type of mechanical force gauge or weighing scale. It consists of a spring fixed at one end with a hook to attach an object at the other. [ 1 ] It works in accordance with Hooke's Law , which states that the force needed to extend or compress a spring by some distance scales linearly with ...
