  2. Ackermann steering geometry - Wikipedia

    en.wikipedia.org/wiki/Ackermann_steering_geometry

    Modern cars do not use pure Ackermann steering, partly because it ignores important dynamic and compliant effects, but the principle is sound for low-speed maneuvers. Some racing cars use reverse Ackermann geometry to compensate for the large difference in slip angle between the inner and outer front tires while cornering at high speed. The use ...

  3. Electrical breakdown - Wikipedia

    en.wikipedia.org/wiki/Electrical_breakdown

    Electrical breakdown in an electric discharge showing the ribbon-like plasma filaments from a Tesla coil.. In electronics, electrical breakdown or dielectric breakdown is a process that occurs when an electrically insulating material (a dielectric), subjected to a high enough voltage, suddenly becomes a conductor and current flows through it.

  4. Headlamp tester - Wikipedia

    en.wikipedia.org/wiki/Headlamp_tester

    A typical headlamp tester. A headlamp tester, also known as headlamp aligner or beam setter, is an instrument to check both the orientation and intensity of a vehicle headlamp beam to ensure that it meets a minimum standard for the country of use of the vehicle.

  5. Dielectric - Wikipedia

    en.wikipedia.org/wiki/Dielectric

    In electromagnetism, a dielectric (or dielectric medium) is an electrical insulator that can be polarised by an applied electric field.When a dielectric material is placed in an electric field, electric charges do not flow through the material as they do in an electrical conductor, because they have no loosely bound, or free, electrons that may drift through the material, but instead they ...

  6. Caster angle - Wikipedia

    en.wikipedia.org/wiki/Caster_angle

    Arthur Krebs proposed placing the front axle of a car at a positive caster angle in his UK patent of 1896, entitled Improvements in mechanically propelled vehicles. In it he stated it was intended "To ensure stability of direction by means of a special arrangement of fore-carriage, that is to say, to re-establish automatically the parallelism of the two axles of the vehicle when there is no ...

  7. Wheel alignment - Wikipedia

    en.wikipedia.org/wiki/Wheel_alignment

    The detailed data provided by 3D systems allows for more intricate adjustments and a more thorough understanding of the vehicle's alignment geometry, particularly suited to 4 wheel drive cars or those needed 4 wheel alignment. Drive-over, Drive-on or Drive Through Wheel Alignment Systems: Next Generation Alignment

  8. Polarization density - Wikipedia

    en.wikipedia.org/wiki/Polarization_density

    When a dielectric is placed in an external electric field, its molecules gain electric dipole moment and the dielectric is said to be polarized. Electric polarization of a given dielectric material sample is defined as the quotient of electric dipole moment (a vector quantity, expressed as coulombs*meters (C*m) in SI units) to volume (meters ...

  9. Relative permittivity - Wikipedia

    en.wikipedia.org/wiki/Relative_permittivity

    The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum. A dielectric is an insulating material, and the dielectric constant of an insulator measures the ability of the insulator to store electric energy in an electrical field.
