The tubes can detect the types of vehicles using the road by measuring the weight that goes over the tubes and the distance between each wheel that rolls over it. Num Lock - Alright, this key has a simple purpose and a majority of you may know what it's for, but probably not know why it's there. When Num Lock is on, your keypad on the right of your keyboard will work like a normal phone dialler, with numbers 0-9 working as normal. The projected things on an aircraft wing - These are called flap track fairings. There are a number of different names for these pods that stick out, including anti-shock bodies or withcomb bodies. These are actually only the covers of the whole mechanism underneath that control the flaps at the back of the wing and they are shaped in this particular way for aerodynamic reasons. Wires extending off airplanes - These are called static dischargers and usually stick out of the trailing edges of aircraft, including the back of wings and tails of airplanes. What they do is prevent the build-up of electric charges around the radio antennas. If these wires weren't there the antennas of the radios would be the most pointy thing sticking out of the plane and since electrons have a tendency to build up where pointy things stick out, charge would build up around radio antennas. Rings on headphone jacks - Each of these are non-conductive insulating rings which basically insulate one section from the next in order to represent which what components get power. Typically, One ring means there are two sections, so the plug is mono and plays the same sound to both stereo headphones and regular stereo headphones will tend to have 2 rings, creating 3 sections, with two of them providing the connection to the left and right speakers. The 'fin' on the roof of cars - These are just cases hiding GPS antennas. Sometimes they're added for aesthetics, but the fin also somewhat helps with aerodynamics. 2 flush buttons - These are dual flush buttons and the toilet experts amongst you are probably just about to comment about how 'everyone should know this one'. But, it's worth explaining just so the few of you who don't know about it... now do, because its features like these that can make a real difference. This is how simple it is - the two buttons flush different amounts of water, so prevent wastage. Tic Tac lids - There's a reason for this tic-tac sort of bed on the inside of the lid. To add ease to retrieving a single mint. Saving you from recklessly shaking out your mints, this ingenious reliefed area allows you to reveal your mints in style by placing the box upside down and opening the lid as you tilt the rest of the box back down. The ball or disk above the rotor on helicopters - This is a Fire Control Radar and is seen on numerous attack helicopters such as the apache. Essentially, it is designed to provide information such as elevation and range to a fire-control system in order to calculate a fire solution. In other words, it detects information on how to direct weapons such that they hit a desired target.
Here's The Only Plane That Could Kill the F-22 Raptor Is the One That Almost Replaced It Both the Raptor and a fully operational F-23 would have carried eight air-to-air missiles internally—that was the Air Force requirement. Moreover, the operational jets were essentially identically in terms of avionics—both competitors had proposed similar avionics suites. In fact, the Raptor ended up with the radar that was originally proposed for the YF-23. Here is a list of signs that actually indicate a super bright mind. They are all scientifically proved, so if you feel like a few of them are true for you, you have every reason to call yourself a genius!

Before arriving at the Airport you're probably not wondering why the airport is designed the way it is. Yet, everything you see in an airport has a purpose. Here’s our top 10 ways airports are designed the way they are, and the purpose of each design secret. Subscribe for more! ► ◄ Stay updated ► ◄ For copyright queries or general inquiries please get in touch: beamazedvideos@gmail Credit: Be Amazed at. Signs - When you’re at the airport, you rely on the signs to point you in the right direction. Walkways - As you’ll see, the reason for many of these designs being the way they are is to prise as much money out of the traveller as possible. The golden hour - Still on moneymaking, let’s explain the concept of the ‘golden hour’. The ‘golden hour’ is what airport managers call the first hour after you’ve cleared security. Windows and lights - Modern airports tend to be designed with lots of glass, such as this one in Indianapolis. Everywhere you turn in new airports, there are huge windows. Departures and arrivals - In most airports, certainly the larger and more modern ones, arrivals is on the ground floor, and departures is on the floor above. Mobile - If you’ve travelled on a plane in the last few years, you’ll know you now have the option to do everything via your phone. Security - Airports are unfortunately prime targets for terrorists, with attackers hitting terminals in Belgium and Turkey over the last couple of years. Floors - Even the floors in airports are designed for a purpose. Firstly there’s wayfinding. In Atlanta, the floor tiles at check-in are coloured to lead you through the airport to the ticket counters. Art - Have you ever wondered why modern airports often contain giant works of art, like this one in Vancouver, or this one in Heathrow? There are many reasons. Queues - When you go to the airport, you’re going to have to queue. It’s a fact of life.
