  2. Circle of forces - Wikipedia

    en.wikipedia.org/wiki/Circle_of_forces

    The circle of forces, traction circle, friction circle, [1] or friction ellipse [2] [3] [4] is a useful way to think about the dynamic interaction between a vehicle's tire and the road surface. The diagram below shows the tire from above, so that the road surface lies in the xy - plane .

  3. Friction - Wikipedia

    en.wikipedia.org/wiki/Friction

    Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. [7] [8] Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. [9] [10] [11] Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body.

  4. Darcy friction factor formulae - Wikipedia

    en.wikipedia.org/wiki/Darcy_friction_factor_formulae

    In fluid dynamics, the Darcy friction factor formulae are equations that allow the calculation of the Darcy friction factor, a dimensionless quantity used in the Darcy–Weisbach equation, for the description of friction losses in pipe flow as well as open-channel flow.

    en.wikipedia.org/wiki/List_of_friction_hitch_knots

    A friction hitch tied around a thicker rope that can slide while unloaded, but locks when loaded. [2] [3] Similar to the Prusik. Michoacan/Martin is a full equivalent to Gripping sailor's hitch: Pile hitch: The pile hitch is easier to tie than the icicle hitch, and can be tied in the bight without access to either end of the rope. Prusik or Prussik

  6. Stribeck curve - Wikipedia

    en.wikipedia.org/wiki/Stribeck_curve

    The discovery and underlying research is usually attributed to Richard Stribeck [1] [2] [3] and Mayo D. Hersey, [4] [5] who studied friction in journal bearings for railway wagon applications during the first half of the 20th century; however, other researchers have arrived at similar conclusions before. The mechanisms along the Stribeck curve ...

  7. Friction motor - Wikipedia

    en.wikipedia.org/wiki/Friction_motor

    A friction motor is a simple mechanism to propel toy cars, trucks, trains, action figures and similar toys. The motor consists of a large flywheel which is connected to the drive wheels of the toy via a gear train with very low gear ratio , so that the flywheel revolves much faster than the wheels.

  8. Key Stage 2 - Wikipedia

    en.wikipedia.org/wiki/Key_Stage_2

    Key Stage 2 is the legal term for the four years of schooling in maintained schools in England and Wales normally known as Year 3, Year 4, Year 5 and Year 6, when the pupils are aged between 7 and 11 years.

  9. Friction loss - Wikipedia

    en.wikipedia.org/wiki/Friction_loss

    The three values chosen for friction loss correspond to, in US units inch water column per 100 feet, 0.01, .03, and 0.1. Note that, in approximation, for a given value of flow volume, a step up in duct size (say from 100mm to 120mm) will reduce the friction loss by a factor of 3.
