    en.wikipedia.org/wiki/M1918_Browning_Automatic_Rifle

    The Browning automatic rifle (BAR) is a family of American automatic rifles and machine guns used by the United States and numerous other countries during the 20th century. . The primary variant of the BAR series was the M1918, chambered for the .30-06 Springfield rifle cartridge and designed by John Browning in 1917 for the American Expeditionary Forces in Europe as a replacement for the ...

  3. Shear force - Wikipedia

    en.wikipedia.org/wiki/Shear_force

    A round bar of steel is used as an example. The shear strength is calculated from the tensile strength using a factor which relates the two strengths. In this case 0.6 applies to the example steel, known as EN8 bright, although it can vary from 0.58 to 0.62 depending on application.

    D500N12 is deformed bar, 500 MPa strength, normal ductility and 12 mm nominal diameter – also known as "N12" Bars are typically abbreviated to simply 'N' (hot-rolled deformed bar), 'R' (hot-rolled round bar), 'RW' (cold-drawn ribbed wire) or 'W' (cold-drawn round wire), as the yield strength and ductility class can be implied from the shape.

  6. Steelyard balance - Wikipedia

    en.wikipedia.org/wiki/Steelyard_balance

    A Scandinavian steelyard is a variant which consists of a bar with a fixed weight attached to one end, a movable pivot point, and an attachment point for the object to be weighed at the other end. Once the object to be weighed is attached to its end of the bar, the pivot point, which is frequently a loop at the end of a cord or chain, is moved ...

  7. Shear stress - Wikipedia

    en.wikipedia.org/wiki/Shear_stress

    The formula to calculate average shear stress τ or force per unit area is: [1] =, where F is the force applied and A is the cross-sectional area.. The area involved corresponds to the material face parallel to the applied force vector, i.e., with surface normal vector perpendicular to the force.

    en.wikipedia.org/wiki/Browning_BAR

    Depending on variant and cartridge, the barrel is 22, 23 or 24 in (560, 580 or 610 mm). Long or Short differ on the action length, and the ShortTrac (BAR ST) can accommodate cartridge lengths up to .308 Winchester, while LongTrac (BAR LT) can accommodate longer cartridges. Since the MK3 update, all BAR rifles have the same long action length ...
