Each is equivalent to 20 hundredweight; however, they are long 51 kilograms (112 lb) or short hundredweight 45 kilograms (100 lb), respectively. Before the 20th century there were several definitions. Prior to the 15th century in England, the ton was 20 hundredweight, each of 108 lb, giving a ton of 2,160 pounds (980 kg).
G is the universal gravitational constant (G ≈ 6.67 × 10 −11 m 3 ⋅kg −1 ⋅s −2 [4]) g = GM / d 2 is the local gravitational acceleration (or the surface gravity , when d = r ). The value GM is called the standard gravitational parameter , or μ , and is often known more accurately than either G or M separately.
The gun fired a 900 g (2.0 lb) high explosive shell at 2,960 ft/s (900 m/s) from a 40 × 311 rimmed cartridge. [22] The rate of fire was normally about 120 rounds per minute (2 rounds per second), which increased slightly when the barrels were closer to the horizon, because gravity assisted the feeding from the top-mounted magazine.
The weight has been reduced to 9.27 kg (20.4 lb), 2.23 kg (4.9 lb) lighter than the M/62. Its rate of fire of around 500–650 rounds per minute (RPM) [ 31 ] is significantly less than the Danish M/62's 1,200 RPM, but it allows for better control, greater accuracy, more conservation of ammunition, more versatile firing positions, and less risk ...
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.
II-210 A light-weight tank (LWT) was first flown on STS-6, which reduced tank weight by 4,700 kg (10,300 lb). The LWT's weight was reduced by removing components from the hydrogen tank and reducing the thickness of some skin panels. [3]: 422 In 1998, a super light-weight ET (SLWT) first flew on STS-91. The SLWT used the 2195 aluminum-lithium ...
After about 700,000 years, some mammals had reached 50 kilos (110 pounds), a 100-fold increase over the weight of those which survived the extinction. [159] It is thought that body sizes of placental mammalian survivors evolutionarily increased first, allowing them to fill niches after the extinctions, with brain sizes increasing later in the ...
