In comparison to the short term, relatively intensive exposures described above, for long-term environmental exposure of the general public there is a limit of 0.08 W/kg averaged over the whole body. [2] A whole-body average SAR of 0.4 W/kg has been chosen as the restriction that provides adequate protection for occupational exposure. An ...
The Kantrowitz limit therefore acts a "speed limit" - for a given ratio of tube area and pod area, there is a maximum speed that the pod can travel before flow around the pod chokes and air resistance sharply increases. [5] In order to break through the speed limit set by the Kantrowitz limit, there are two possible approaches.
In unit systems where force is a derived unit, like in SI units, g c is equal to 1. In unit systems where force is a primary unit, like in imperial and US customary measurement systems , g c may or may not equal 1 depending on the units used, and value other than 1 may be required to obtain correct results.

The KE-W round is known for its exceptional armor-penetrating capabilities, utilizing kinetic energy to defeat armored targets. It is commonly used by modern main battle tanks as their primary anti-tank ammunition. The round is mainly used on the NATO 120x570mm cannons. The main users are the American Abrams tank, and the German Leopard [3] tank.
For acrobatic category airplanes, from −3.0 to +6.0 [6] For helicopters, from −1 to +3.5 [7] [8] However, many aircraft types, in particular aerobatic airplanes, are designed so that they can tolerate load factors much higher than the minimum required. For example, the Sukhoi Su-26 family has load factor limits of −10 to +12. [9]
A newton is equal to 1 kg⋅m/s 2, and a kilogram-force is 9.80665 N, [3] meaning that 1 kgf/cm 2 equals 98.0665 kilopascals (kPa). In some older publications, kilogram-force per square centimetre is abbreviated ksc instead of kg/cm 2 .
