Aerodynamics help reduce drag so the engines can produce thrust.

How does ballistics help police solve crimes?

Rifling marks, the marks etched into a bullet as it travels through a gun's barrel, are to a gun as fingerprints are to a person. To see if a fired round came from a particular gun, the gun is test fired into a pool of water (to stop the bullet without changing its shape) then the marks on the test fired bullet and the bullet in question are compared. Knowing the trajectory of a bullet points you in the direction of its origination. There are also some clues that will help you determine from how far a shot was fired, such as approximate speed on impact and the presence of burnt gunpowder.

you better find because doctors don't know what there doing


How does a hollow point bullet work?

When a hollow-point hunting bullet strikes a soft target, the pressure created in the pit forces the material (usually lead) around the inside edge to expand outwards, increasing the axial diameter of the projectile as it passes through. This process is commonly referred to as mushrooming, because the resulting shape, a widened, rounded nose on top of a cylindrical base, typically resembles a mushroom.The greater frontal surface area of the expanded bullet limits its depth of penetration into the target, and causes more extensive tissue damage along the wound path. Many hollow-point bullets, especially those intended for use at high velocity in centerfire rifles, are jacketed, i.e. a portion of the lead-cored bullet is wrapped in a thin layer of harder metal, such as copper or mild steel. This jacket provides additional strength to the bullet, and can help prevent it from leaving deposits of lead inside the bore. Incontrolled expansion bullets, the jacket and other internal design characteristics help to prevent the bullet from breaking apart; a fragmented bullet will not penetrate as far.

In what ways can aerodynamic helped some sports?

For biking, aerodynamics means less drag force (the force that opposes motion when an object moves through a liquid or gas). The less opposition to motion, the faster you can move. This can also help in sports like baseball, because you need to be able to move as fast as possible. Aerodynamics on boats and race cars can increase fuel efficiency and speed.


Does a hood scoop actually enhance a car’s aerodynamics?

A functioning hood scoop is not in place to increase the aerodynamics of a car. It is system to help force more air into the intake of the car’s engine, making in go faster.

How manufacturer selects the wing on aircraft?

It is based on the aerodynamics of the wing. The engineers will select the best wing that fits the main mission of the aircraft they are building in order to take full advantage of the wing. Some wings are more efficient when flying slow and some are better when flying fast. Wings that help you go fast tend to stall sooner when flying slow than wings that help you go slow for example.
