The boiler was designed to be the maximum possible size that could fit within C&O clearance envelopes. It sported an outside diameter of 109 in (2.8 m), 2 in (51 mm) wider than the Union Pacific Big Boy , carried 23 ft (7.0 m) tubes and flues, one foot longer than Big Boy, and was designed with a maximum operating pressure of 265 psi (1.83 MPa ...
November 14, 1935. The Noorduyn Norseman, also known as the C-64 Norseman, is a Canadian single-engine bush plane designed to operate from unimproved surfaces. Distinctive stubby landing gear protrusions from the lower fuselage make it easily recognizable. Introduced in 1935, the Norseman remained in production for almost 25 years with over 900 ...
Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake. These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location. Magnitudes are usually determined from measurements of an earthquake's seismic ...
In 1824, these units were replaced with a single system based on the imperial gallon. [a] Originally defined as the volume of 10 pounds (4.54 kg) of distilled water (under certain conditions), [b] then redefined by the Weights and Measures Act 1985 to be exactly 4.546 09 L (277.4 cu in), the imperial gallon is close in size to the old ale gallon.
The metric system is a decimal -based system of measurement. The current international standard for the metric system is the International System of Units (Système international d'unités or SI), in which all units can be expressed in terms of seven base units: the metre (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and ...
The Commodore 64, also known as the C64, is an 8-bit home computer introduced in January 1982 by Commodore International (first shown at the Consumer Electronics Show, January 7–10, 1982, in Las Vegas). [4] It has been listed in the Guinness World Records as the highest-selling single computer model of all time, [5] with independent estimates ...
The gal is a derived unit, defined in terms of the centimeter–gram–second (CGS) base unit of length, the centimeter, and the second, which is the base unit of time in both the CGS and the modern SI system. In SI base units, 1 Gal is equal to 0.01 m/s 2. The acceleration due to Earth's gravity at its surface is 976 to 983 Gal, the variation ...
The Class 16 4-6-2 Pacific type passenger locomotive was designed by D.A. Hendrie, Chief Mechanical Engineer (CME) of the South African Railways (SAR) from 1910 to 1922.
