armored glass urban buildings are subject to different security requirements depending on the purpose for which the building is used when it comes to luxury shops banks or other facilities that need to be well protected perhaps the most common measure to improve security is the installation of anti-theft glass there are different levels of protection the lowest level for example is designed to withstand between 30 and 50 hits with blunt or sharp objects the medium level can withstand 50 to 70 heads and the highest level will withstand more than 70 hits this level of resistance is usually sufficient to protect the building from intruders or at least to delay them long enough to be able to call the police in time of course to be sure of the quality of the products the companies that manufacture this type of glass carry out tests from time to time in this case that says to the glass by British company ESG glasses shown see how 13 millimeter glass of the highest class p8b can withstand the intense impact of a crowbar hammers and an axe the test takes a minutes and a half and the glass crumbles little by little but it doesn't lose its integrity the secrets of the resistance lies in a complex special construction the manufacturer uses several layers of glass which are glued with a special polymer film this allows the impact energy to be distributed evenly over the surface keeping the broken glass pieces in place Cessna 172 the video shows the crash test of the American light aircraft Cessna 172 Skyhawk the aircraft was launched against a concrete surface from a height of 25 meters the test was conducted in the city of Hampton Virginia at the Langley Research Center owned by NASA three emergency beacons were installed on board the purpose of the event was to test them in particular these beacons transmit the distress signal to the search and rescue forces in recent years the technology incorporated into these beacons has improved significantly now the beacons can transmit their own coordinates using information from onboard equipment or satellite systems the radio beacon can be activated manually or automatically when an emergency situation is detected remarkably there's no way to cancel the distress signal sent even if the beacon is turned off and the signal is lost unfortunately the sensor doesn't always transmit the signal correctly and accurately that's why research and testing are still ongoing and scientists are working to minimize the probability of error superhydrophobic protective layer although the objects shown in this video may seem water-resistant it's actually a little more complicated than that there is a concept known as ultra hydrophobicity this word denotes the wettability determined by the angle formed between the surface of the material and the surface of the droplets at the points of contact if the angle is less than 90 degrees then the material is hydrophilic it can be wetted with water if the angle is 90 degrees to 150 degrees then the material is hydrophobic it is possible to wet it but it's not easy and finally when the angle exceeds a hundred and fifty degrees and the drop at the moment of contact has an almost spherical shape the material is ultra hydrophobic and impossible to wet the drops are repelled or roll off the surface leaving no traces the video shows a protective layer which allows any material to acquire super hydrophobic properties the invention is called ultra ever dry and it's patented technology creates an air barrier on the protected surface that repels water juices oil and any other liquid flood barriers the chance that people will stop suffering from a natural disaster such as a flood is very small floods are natural processes caused by prolonged rains tsunamis and melting snow this is a global problem so Humanity is inventing new ways to reduce the material damage to the economy and the social sphere caused by floods the NOAA cube box wall is a barrier specifically designed to protect buildings from flooding although barriers have been used for a long time the NOAA cubox wall has a unique design with many advantages the barrier consists of individual components each weighing less than three and a half kilograms despite the low weight and ease of installation the NOAA cubox wall provides reliable protection as it's 50 centimeters tall the system is easy to install as it appears to a solid flat surface by itself when the water starts to rise of course before claiming that the Noa cubox wall can save property and even lives many tests must be carried out artificially a powerful flow of water is created and then the barrier effectively diverts it to the sides fortified home other natural disasters that people face too often are tornadoes a tornado formed in a storm cloud moves at speeds ranging from 20 to 60 km/h and the wind can accelerate to more than 300 km/h one of the highest wind speed recorded was 485 km/h it should be noted that at wind speeds of more than a hundred km/h even the strongest buildings begin to collapse fortunately really dangerous tornadoes don't appear every day and people are looking for new ways to strengthen buildings and protect them from destruction there's a program called fortified home that helps people strengthen their house engineering and construction standards have been developed for more than 20 years and during this time tests have been conducted to demonstrate the stability of the design the tests are performed at a special chamber with a machine capable of simulating a natural disaster for example scientists from Florida International University have built the wall of wind 12 powerful giant fans accelerate the when to the speed of a category 5 hurricane carpets action and here's another artifact also designed to protect your belongings from flooding sometimes even driving through a deep puddle can lead to a car break down and then expensive repairs in the event of a flood water always enters the vehicle causing it to break down fortunately today a fairly large number of companies are developing special banks that could protect your vehicle from flooding they're made of durable waterproof fabric and are securely attached to the surface of the car some even have special handles for tying the cattle tree the bags are tested using special pools tanks are built around the car packed in the protective bag and then filled with water after a while the water is drained and you can see the car has not been damaged by the water at all hey stop being lazy it's time to use that brain of yours welcome to brain time incredible facts from the past the present and even the future the power of nature and wild animals amazing facts and unsolved mysteries you'll find all this and much more hair subscribe now you won't regret it
