  2. Turning radius - Wikipedia

    en.wikipedia.org/wiki/Turning_radius

    Diagram of turning vehicle. On wheeled vehicles with the common type of front wheel steering (i.e. one, two or even four wheels at the front capable of steering), the vehicle's turning diameter measures the minimum space needed to turn the vehicle around while the steering is set to its maximum displacement from the central 'straight ahead' position - i.e. either extreme left or right.

  3. Minimum railway curve radius - Wikipedia

    en.wikipedia.org/wiki/Minimum_railway_curve_radius

    The minimum railway curve radius is the shortest allowable design radius for the centerline of railway tracks under a particular set of conditions. It has an important bearing on construction costs and operating costs and, in combination with superelevation (difference in elevation of the two rails) in the case of train tracks , determines the ...

  4. Ackermann steering geometry - Wikipedia

    en.wikipedia.org/wiki/Ackermann_steering_geometry

    Ackermann geometry. The Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii.

  5. Banked turn - Wikipedia

    en.wikipedia.org/wiki/Banked_turn

    The radius of the turn can now be calculated: [5] = ⁡ This formula shows that the radius of turn is proportional to the square of the aircraft's true airspeed. With a higher airspeed the radius of turn is larger, and with a lower airspeed the radius is smaller.

  6. Turn (angle) - Wikipedia

    en.wikipedia.org/wiki/Turn_(angle)

    The turn (symbol tr or pla) is a unit of plane angle measurement that is the measure of a complete angle—the angle subtended by a complete circle at its center. One turn is equal to 2π radians, 360 degrees or 400 gradians. As an angular unit, one turn also corresponds to one cycle (symbol cyc or c) [1] or to one revolution (symbol rev or r). [2]

    Special customization options (think back support, footplates, and headrest), seat width, turning radius, and weight capacity are all thoughtful features that ensure the user is comfortable and safe.

  8. Quadrasteer - Wikipedia

    en.wikipedia.org/wiki/Quadrasteer

    The system was primarily used on pickup trucks. At lower speeds, it turns in opposite direction of the forward wheels to a maximum of 15°, or 12° in trailer mode, decreasing the turning radius as much as 21%. At higher speeds the system will turn the rear wheels slightly in the direction of the front wheels so as to increase stability and ...
