  2. Axle load - Wikipedia

    en.wikipedia.org/wiki/Axle_load

    The standard rail weight for British railways is now 113 lb/yd (56.1 kg/m). Before the 1990s, most diesel locomotives were built to a maximum axle load of 19 long tons (19.3 tonnes; 21.3 short tons) so the maximum locomotive weight was 76 long tons (77.2 tonnes; 85.1 short tons) for a four-axle locomotive and 114 long tons (115.8 tonnes; 127.7 short tons) for a six-axle one.

  3. Chassis configuration - Wikipedia

    en.wikipedia.org/wiki/Chassis_configuration

    - = separates axle groups and/or different axle functions (6x4-2 is 6x6 with undriven rear axle) Basis is always the standard configuration, meaning a steered front axle and a non-steered driven rear axle. This means: If only the front wheels are steered, the rearmost part of the formula can be left out.

  4. Vehicle weight - Wikipedia

    en.wikipedia.org/wiki/Vehicle_weight

    In the EU a tractor can generally have 10 tonnes (22,000 lb) on a single axle, with suspension type and number of tires often allowing slightly higher loads. In the U.S. weight restrictions are generally 20,000 pounds (9,100 kg) on a single axle, and 34,000 pounds (15,000 kg) (less than two single axles) on a tandem.

  5. Fourth power law - Wikipedia

    en.wikipedia.org/wiki/Fourth_power_law

    When evaluating the series of tests, it was found that there is a connection between the thickness of the pavement, the number of load transfers and the axle load, and that these have a direct effect on the service life and condition of a road. The service life of the road is thereby reduced with approximately the fourth power of the axle load. [1]

  6. 1Co+Co1 - Wikipedia

    en.wikipedia.org/wiki/1Co+Co1

    South African Class 32-000 diesel-electric. Under the British and Imperial classification scheme of locomotive axle arrangements 1Co+Co1 is a classification code for a locomotive wheel arrangement of two eight-wheeled bogies with an articulated inter-bogie connection, each with three axles powered by a separate traction motor per axle and with the fourth non-powered axle in an integral leading ...

    The same chassis must then sustain a rear impact from a sled travelling at 30 mph (48 km/h), with no damage in front of the rear axle. [3] The roll hoop is not permitted to crush beyond 50 mm (2.0 in), and structural failure is only permitted in the top 100 mm (3.9 in) of the body. [ 4 ]

  8. Co-Co locomotive - Wikipedia

    en.wikipedia.org/wiki/Co-Co_locomotive

    The 1Co-Co1 wheel arrangement is an alternative to the Co-Co arrangement which has been used where it was desired to reduce axle load. Each 'Co' bogie has an additional non-powered axle in an integral pony truck to spread the load. As the pony truck is articulated within the bogie, [3] the arrangement is (1′Co)(Co1′) in UIC notation.

  9. Formula One car - Wikipedia

    en.wikipedia.org/wiki/Formula_One_car

    A modern Formula One car capable of developing up to six G of lateral cornering force and a downforce equivalent to twice its weight at 190 km/h (120 mph). [65] [66] The car is designed to create the maximum amount of downforce for the minimal amount of drag with the configuration often modified to the requirements of a particular track. [58]
