Molotovs are extremely dangerous, both to anyone who may be hit by one, and to someone who makes them or throws them. The scars left can leave someone waking up each and every morning for the rest of their life being afraid to look into the mirror because of the sight that is reflected back at them. The Molotov cocktail or petrol bomb is a weapon. It is not a beverage, and it is certainly not a toy. Actually, it is not a bomb as such, as a bomb requires an explosion, and combustion is not quick enough to cause an explosion. Come to that, it doesn't have to contain petrol either, so it should be more accurately referred to as an 'inflammable liquid incendiary device'.
ReplyDeleteWhen a Molotov hits something hard, like a wall or the ground, the bottle shatters, and the liquid is spilled and covers the nearby area. The burning rag, which has been tied to the neck of the bottle, will then ignite the liquid and cause a fire. The shards of glass can be nasty in themselves, and the resulting fire can cause severe burns.
Until the bottle shatters, the liquid within it is insulated from the heat of the burning rag by the bottle, so it is possible to hold onto a lighted Molotov for some time. However, there is a real danger of the liquid spontaneously igniting, causing untold damage to the hand of the would-be thrower. There is also a risk of dropping the bottle as it heats up, with similar results.

quartz:
ReplyDeleteQuartz crystals have electrical properties; they develop an electric potential upon the application of mechanical stress. An early use of this property of quartz crystals was in phonograph pickups.The quartz clock is a familiar device using the mineral.

A gasoline engine operates on the principle of combustion. A fuel mixture is pulled into a cylinder, the cylinder is then closed off and the piston is thrust upward to create compression. A spark is introduced to ignite the mixture to create combustion to thrust the piston downward in the engine block.
ReplyDeleteFor a car to turn smoothly, each wheel must follow a different circle. Since the inside wheel is following a circle with a smaller radius, it is actually making a tighter turn than the outside wheel. If you draw a line perpendicular to each wheel, the lines will intersect at the center point of the turn. The geometry of the steering linkage makes the inside wheel turn more than the outside wheel.
The pinion gear is attached to the steering shaft. When you turn the steering wheel, the gear spins, moving the rack. The tie rod at each end of the rack connects to the steering arm on the spindle.
