The Federal Bridge Gross Weight Formula, also known as Bridge Formula B or the Federal Bridge Formula, is a mathematical formula in use in the United States by truck drivers and Department of Transportation (DOT) officials to determine the appropriate maximum gross weight for a commercial motor vehicle (CMV) based on axle number and spacing.
Mud weight. In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . [1] In the field it is measured using a mud scale or mud balance. Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds (or 7.48 ppg). In ...
In the well-known formula P = 0.052 * mud weight * true vertical depth. taught in almost all petroleum engineering courses worldwide, the mud weight (MW) is expressed in pounds per U.S. gallon, and the true vertical depth (TVD) is expressed in feet, and 0.052 is a commonly used conversion constant that can be derived by dimensional analysis:
The "Three-quarter-tonner" appeared in the Ford truck lineup in 1939. [22] Over time, payload capacities for most domestic pickup trucks have increased while the ton titles have stayed the same. The 1948 Ford F-1 had a Gross Vehicle Weight Rating (GVWR) of 4700 pounds. [23] The truck was marketed with a "Nominal Tonnage Rating: Half-Ton."
Dry weight is the weight of a vehicle without any consumables, passengers, or cargo. It is significantly less than the weight of a vehicle in a drivable condition and therefore rarely used. Quoting a dry weight can make a car's weight and power-to-weight figures appear far more favorable than those of rival cars using curb weight. [4] [5]
As a good approximation the chemical formula of diesel is C n H 2n. Diesel is a mixture of different molecules. As carbon has a molar mass of 12 g/mol and hydrogen has a molar mass of about 1 g/mol, so the fraction by weight of carbon in EN 590 diesel fuel is roughly 12/14. The reaction of diesel combustion is given by: 2 C n H 2n + 3n O 2 ⇌ ...
Medium trucks are larger than light but smaller than heavy trucks. In the US, they are defined as weighing between 14 001– 26 000 lb (6 351– 11 793 kg). In North America, a medium-duty truck is larger than a heavy-duty pickup truck or full-size van. Some trucks listed as medium also are made in heavy versions. Box truck; Van; Cutaway van ...
A dump truck with continuous track wheels crosses a river and dumps its load in Kanagawa, Japan. An agricultural tractor with rubber tracks, mitigating soil compaction. A Russian tracked vehicle designed to operate on snow and swamps. A British Army Challenger 1 tank. Continuous track or tracked treads are a system of vehicle propulsion used in ...
