For example, if a shaft with a nominal diameter of 10 mm is to have a sliding fit within a hole, the shaft might be specified with a tolerance range from 9.964 to 10 mm (i.e., a zero fundamental deviation, but a lower deviation of 0.036 mm) and the hole might be specified with a tolerance range from 10.04 mm to 10.076 mm (0.04 mm fundamental ...
Limits and Fits are standardized by the International Organization for Standardization (ISO) [2] and the American National Standards Institute (ANSI). [3] Tables are used to quickly calculate required tolerances for bolt holes, shafts, mating parts, and many similar scenarios.
The 30-degree rule is a basic film editing guideline that states the camera should move at least 30 degrees relative to the subject between successive shots of the same subject. If the camera moves less than 30 degrees, the transition between shots can look like a jump cut —which could jar the audience and take them out of the story.
Gunter's chain was 66 feet, or one chain (20.1 metres), in length (i.e. one tenth of a furlong) and consisted of 100 links, making each link 1 ⁄ 1000 furlong (201 millimetres). The decimal nature of these units and of the device made it easy to calculate the area of a rectangle of land in acres and decimal fractions of an acre.
An association football pitch may vary within limits of 90–120 m (98–131 yd) in length and 45–90 m (49–98 yd) in width. The recommended field size is 105 m × 68 m (115 yd × 74 yd) for major competitions such as the FIFA World Cup , UEFA European Championship and UEFA Champions League .
In sailing, the limit of positive stability (LPS) or angle of vanishing stability (AVS) is the angle from the vertical at which a boat will no longer stay upright but will capsize, becoming inverted, or turtled.
90-foot (27.43 m) radii on the elevated 4 ft 8 + 1 ⁄ 2 in (1,435 mm) standard gauge Chicago 'L'. There is no room for longer radii at this cross junction in the northwest corner of the Loop . The minimum railway curve radius is the shortest allowable design radius for the centerline of railway tracks under a particular set of conditions.
For example, such a regulation might limit the concentration of NOx to 55 ppmv in a dry combustion exhaust gas corrected to 3 volume percent O 2. As another example, a regulation might limit the concentration of particulate matter to 0.1 grain per standard cubic foot (i.e., scf) of dry exhaust gas corrected to 12 volume percent CO 2.
