Also isometric graphics. Graphic rendering technique of three-dimensional objects set in a two-dimensional plane of movement. Often includes games where some objects are still rendered as sprites. 360 no-scope A 360 no-scope usually refers to a trick shot in a first or third-person shooter video game in which one player kills another with a sniper rifle by first spinning a full circle and then ...
1: Aerodynamic cover; 2: Air-filled cavity; 3: Conical liner (Often copper); 4: Detonator; 5: Explosive; 6: Piezo-electric trigger. High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the ...
[1] The first usage of the term "flak jacket" refers to the armor originally developed by the Wilkinson Sword company during World War II to help protect Royal Air Force (RAF) aircrew from the flying debris and shell fragments thrown by German anti-aircraft guns ' high-explosive shells ( flak itself is an abbreviation for the German word ...

These wheels, also called pinwheels, could be set by using a side lever which could expose anywhere from 0 to 9 teeth, and therefore when coupled to a ...
The decision whether to construct a tunnel using a TBM or using a drill and blast method includes a number of factors. Tunnel length is a key issue that needs to be addressed because large TBMs for a rock tunnel have a high capital cost, but because they are usually quicker than a drill and blast tunnel the price per metre of tunnel is lower.

The jet cuts any material in its path, to a depth depending on the size and materials used in the charge. Generally, the jet penetrates around 1 to 1.2 times [56] the charge width. For the cutting of complex geometries, there are also flexible versions of the linear shaped charge, these with a lead or high-density foam sheathing and a ductile ...

A value of 0 is given for non-explosive eruptions, defined as less than 10,000 m 3 (350,000 cu ft) of tephra ejected; and 8 representing a supervolcanic eruption that can eject 1.0 × 10 12 m 3 (240 cubic miles) of tephra and have a cloud column height of over 20 km (66,000 ft). The scale is logarithmic, with each interval on the scale ...
