Specific surface area (SSA) is a property of solids defined as the total surface area (SA) of a material per unit mass, [1] (with units of m 2 /kg or m 2 /g). Alternatively, it may be defined as SA per solid or bulk volume [ 2 ] [ 3 ] (units of m 2 /m 3 or m −1 ).
The M2 was intended to bridge the gap between the 81 mm mortar and the hand grenade. Normally employed by the weapons platoon of a U.S. infantry company, the M2 is of the usual mortar pattern of the day. [1] [2] It consists of a smoothbore metal tube on a rectangular baseplate, supported by a simple bipod with the elevation and traverse mechanisms.
[citation needed] In the concrete and petroleum industry, however, a bag of cement is defined as 94 lb (43 kg) because it has an apparent volume close to 1 cubic foot (28 litres). [61] When ready-mix concrete is specified, a "bag mix" unit is used as if the batching company mixes 5 literal bags of cement per cubic yard (or cubic metre) when a ...
A cylinder of foam concrete. Foam concrete, also known as Lightweight Cellular Concrete (LCC) and Low Density Cellular Concrete (LDCC), and by other names, is defined as a cement-based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar. [1]
T1IDP = 210 cartridges .50 linked (4 × AP M2, 1 × TR M1), 105 linked rounds in metal M2 ammo box, 2 × M2 ammo boxes per wooden crate. Volume: 0.93 Cubic Feet. T1IDS = 110 cartridges .50 linked (2 × AP-I M8, 2 × INC M1, 1 TR M10), 55 linked rounds in metal M10 ammo can, 2 × M10 ammo cans per M12 wooden crate.
Because of the difference in available volume, a smooth-bore mortar of a given diameter will have a greater explosive yield than a similarly sized artillery shell of a gun or howitzer. For example, a 120 mm mortar bomb has approximately the same explosive capability as a 152 mm/155 mm artillery shell.
It was adopted due to the extended range and lethality in comparison to the previous M2 mortar, although the M30, at 305 kilograms (672 lb), was significantly heavier than the 151 kilograms (333 lb) M2. Due to this heavy weight, the mortar was most often mounted in a tracked mortar carrier of the M113 family, designated as the M106 mortar ...
The 120mm M2 Rifled Heavy Mortar (Portuguese: Morteiro Pesado 120mm M2 raiado) is a Brazilian 120 mm mortar designed to have great firepower, mobility, and flexibility. The RT-M2 is designed by the War Arsenal of Rio de Janeiro for the Brazilian Army artillery . [ 1 ]
