For example, the French livre, until 1812, had a mass of 489.5 g (1.079 lb), whilst the contemporary English (avoirdupois) pound massed of approximately 454 g (1.001 lb). Thus, a French 32-pounder at the Battle of Trafalgar threw a shot with 1.138 kg (2.51 lb) more mass than an English 32-pounder.
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
The B-17's armament consisted of five .30 caliber (7.62 mm) machine guns, with a payload up to 4,800 lb (2,200 kg) of bombs on two racks in the bomb bay behind the cockpit. The aircraft was powered by four Pratt & Whitney R-1690 Hornet radial engines , each producing 750 hp (600 kW) at 7,000 ft (2,100 m).
The Model 100 is a stretched derivative of the Model 90 featuring five cabin windows instead of the Model 90's three; MTOW increased by 1,300 lb (590 kg) over the 90, to 10,600 lb (4,810 kg). The 100 used the wings, tail, and engines (two PT6A-28 engines, although rated at 680 shp) [ 17 ] from the Model 99 airliner, itself a development of the ...
The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]
Series 2 bombers also differed from the Series 1 in having an increased payload of four 500 lb (230 kg) bombs, instead of the four 250 lb (110 kg) bombs of Series 1. This was made possible by cropping , or shortening the tail of the 500 lb (230 kg) bomb so that these four heavier weapons could be carried (or a 2,000 lb (920 kg) total load). [ 163 ]
In the countries of the former USSR, 65 kg/m (131 lb/yd) rails and 75 kg/m (151 lb/yd) rails (not thermally hardened) are common. Thermally hardened 75 kg/m (151 lb/yd) rails also have been used on heavy-duty railroads like Baikal–Amur Mainline , but have proven themselves deficient in operation and were mainly rejected in favor of 65 kg/m ...
Consequently, the Rafale M weighs about 500 kg (1,100 lb) more than the Rafale C. [35] [39] It is the only non-US fighter type cleared to operate from the decks of US carriers, using catapults and their arresting gear, as demonstrated in 2008 when six Rafales from Flottille 12F integrated into the USS Theodore Roosevelt Carrier Air Wing ...
