  2. Pitch angle - Wikipedia

    en.wikipedia.org/wiki/Pitch_angle

    Pitch angle (engineering), the angle between a bevel gears' element of a pitch cone and its axis; Pitch angle (particle motion), the angle between a charged particle's velocity vector and the local magnetic field; Pitch angle (kinematics), the rotation about the transverse axis of a stiff body Pitch angle (aviation), an airplane's rotation ...

  3. Pitch angle (particle motion) - Wikipedia

    en.wikipedia.org/wiki/Pitch_angle_(particle_motion)

    It is customary to discuss the direction a particle is heading by its pitch angle. A pitch angle of 0 degrees is a particle whose parallel motion is perfectly along the local magnetic field. In the northern hemisphere this particle would be heading down toward the Earth (and the opposite in the southern hemisphere). A pitch angle of 90 degrees ...

  4. Pitch angle of a spiral - Wikipedia

    en.wikipedia.org/wiki/Pitch_angle_of_a_spiral

    In the geometry of spirals, the pitch angle [1] or pitch [2] of a spiral is the angle made by the spiral with a circle through one of its points, centered at the center of the spiral. Equivalently, it is the complementary angle to the angle made by the vector from the origin to a point on the spiral, with the tangent vector of the spiral at the ...

  5. List of gear nomenclature - Wikipedia

    en.wikipedia.org/wiki/List_of_gear_nomenclature

    A shaft angle is the angle between the axes of two non-parallel gear shafts. In a pair of crossed helical gears, the shaft angle lies between the oppositely rotating portions of two shafts. This applies also in the case of worm gearing. In bevel gears, the shaft angle is the sum of the two pitch angles

  6. Bevel gear - Wikipedia

    en.wikipedia.org/wiki/Bevel_gear

    The pitch surface of an ordinary gear is the shape of a cylinder. The pitch angle of a gear is the angle between the face of the pitch surface and the axis. The most familiar kinds of bevel gears have pitch angles of less than 90 degrees and therefore are cone-shaped. This type of bevel gear is called external because the gear teeth point ...

  7. Pitch - Wikipedia

    en.wikipedia.org/wiki/Pitch

    Pitch (baseball), a throw of a baseball from a pitcher to the catcher(s) Pitch (card game) (or "High, or Low Jack"), an American trick-taking card game; Pitch (sports field), a field of play and is usually outdoors Cricket pitch; Rugby pitch; Football pitch; The bounce of a cricket ball; Pitch, a lateral pass in gridiron football

  8. Grade (slope) - Wikipedia

    en.wikipedia.org/wiki/Grade_(slope)

    α = angle of inclination. The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal or its tangent. It is a special case of the slope, where zero indicates horizontality. A larger number ...

  9. Helix angle - Wikipedia

    en.wikipedia.org/wiki/Helix_angle

    In helical and worm gears, the helix angle denotes the standard pitch circle unless otherwise specified. [1] Application of the helix angle typically employs a magnitude ranging from 15° to 30° for helical gears, with 45° capping the safe operation limit. The angle itself may be cut with either a right-hand or left-hand orientation. [5]
