However, because the difference between wet and dry is half-a-second at 30 MPH and one second at 60 MPH, and because dividing by two is easier than three, we can use a correctable rule of thumb: t ≈ v 20 + 1 (general rule of thumb) {\displaystyle \color {Sepia}{t\approx {\frac {v}{20}}+1\quad {\text{(general rule of thumb)}}}} (instead add 2 ...
Simpson's rules are used to calculate the volume of lifeboats, [6] and by surveyors to calculate the volume of sludge in a ship's oil tanks. For instance, in the latter, Simpson's 3rd rule is used to find the volume between two co-ordinates. To calculate the entire area / volume, Simpson's first rule is used. [7]
In aviation, the rule of three or "3:1 rule of descent" is a rule of thumb that 3 nautical miles (5.6 km) of travel should be allowed for every 1,000 feet (300 m) of descent. [1] [2] For example, a descent from flight level 350 would require approximately 35x3=105 nautical miles. This would have to be adjusted for headwind or tailwind, [1] and ...
Like the Hombre, which was based on the compact Chevrolet S-10/GMC Sonoma, the i-series was based on the Chevrolet Colorado/GMC Canyon. Two models were offered at launch: the i-280, powered by the 2.8 L I4 engine, and the i-350, powered by the 3.5 L I5 engine. The i-280 was available only with an extended cab, while the i-350 could be had with ...
Mallett started the project by sourcing a twin-turbocharged, 3.6-liter V6 from Cadillac's brilliant ATS-V and completely tearing it down. Its mechanics rebuilt it with a forged crankshaft, forged ...
The tallest building in Denver is the 56-story Republic Plaza, which rises 717 feet (219 m) and was completed in 1984. [1] It stands as the 137th-tallest building in the United States, and the tallest building in the State of Colorado. The second-tallest skyscraper in the city and the state is 1801 California Street, which rises 709 feet (216 m).
The DMU is powered by two Detroit Diesel engines with a combined 1,200 horsepower (890 kilowatts). Each DMU is capable of traveling up to 100 mph (160 km/h). The DMU is 85 ft (26 m) long with a height of 14 ft 10 in (4.52 m) (19 ft 6 in (5.94 m) for the bi-level DMU). The DMU has 92 seats (190 for the bi-level).
For higher speeds up to about 100 km/h outside built-up areas, a similarly defined 2-second rule applies, which for 100 km/h translates to about 50 m. For speeds on the order of 100 km/h there is also the more or less equivalent rule that the stopping distance be the speed divided by 2 k/h, referred to as halber tacho ( half the speedometer ...
