CULTURAL QA 05-2023-04 Q1 Why aren't the reartires on cars made to turn like the front tires?
A1 Erika Fernandez, CarLover Sun The reason rear tires on cars are not made to turn like the front tiresis because of the way cars are designed and engineered. The front tires are responsible for steering the car and changing itsdirection, while the rear tires provide power to the car and help it moveforward. Having rear tires that can turn like the front tires would add complexityand cost to the car's design and manufacturing process. It would requireadditional components such as a rear steering mechanism, which would increasethe weight of the car and potentially decrease its performance and fuelefficiency. Also, the benefits of having rear tires that can turn are insignificantcompared to the added cost and complexity. While it may provide some advantages in terms of manoeuvrability andhandling in certain situations, such as tight parking spots, the benefits donot outweigh the drawbacks in most driving scenarios. Q2 Why is fuel stored inthe wings of the aircraft? A2 Vishnu Ravi, BE inAerospace and Aeronautical Engineering, Anna University, Tamil Nadu, India(Graduated 2015)22h Fuel is stored in the wings ofan aircraft for several reasons. Firstly, the fuel tanks increase the rigidity of thewings and spread the total take-off weight more evenly across the aircraft,providing strength and stability during take-off. Secondly, the fuel acts ascounter stress for the wingsshortly after take-off when the great stress of the aircraft's mass acts onthem, preventing a momentous change in the wing dihedral angle. Thirdly, havingthe fuel in the wings keeps it away from the cabin and the occupants, reducingrisks of cabin fires in the event of a crash landing. Finally, the storage of fuel inthe wings helps to preventwing bending stresses, and wing tank fuel is used last during the flight. Q3 What animal is therethe most of on earth? A3 Animal Lover | DogLover | Cat Lover | Loving Husband Sun The earth is home to anincredibly diverse range of species, with estimates suggesting that there maybe anywhere from 8.7 million to thirty million species living on our planet. However, when it comes to theanimal kingdom, there is one species that stands out as the most numerous: thenematode. Nematodes, also known asroundworms, are a type of invertebrate that are found in every environment onearth. They are incredibly small, measuring just few millimetresin length, but they are incredibly numerous. In fact, it is estimated thatthere may be as many as one million nematode species on earth, with someestimates suggesting that there could be up to one hundred billion individualnematodes for every human on the planet. So why are nematodes sonumerous? There are few factorsthat contribute to their incredible abundance. For one, they are incrediblyresilient and adaptable. Theyare found in every type of environment on earth, from the depths of the oceanto the soil in your backyard. They can survive in extremetemperatures, elevated levels of radiation, and even in the vacuum of space. Another reason nematodes are sonumerous is their reproductive rate. Nematodes are incredibly prolific breeders, with some species layingtens of thousands of eggs in a single day. They also have a noticeably short lifespan, with somespecies living for just a few days. This means that they canreproduce quickly and efficiently, and their populations can grow rapidly. Nematodes also play a key rolein many ecosystems. They are avital part of the food chain, serving as a food source for many predators,including birds, fish, and other invertebrates. They also play a critical rolein soil health, helping to break down organic matter and cycling nutrients backinto the soil. While nematodes may not be themost charismatic or well-known animals on earth, their incredible abundance andadaptability make them a vital part of our planet's ecosystems. They may be small, but they are mighty, and theirimportance cannot be overstated. Q4 What are some mind-blowingfacts that most people do not know?

Q6 Why aren't commercialairplanes fully automated yet? i.e., take-off, fly and land all without aregular human pilot. A6 John Richards, Privatepilot with an instrument and multi-Engine rating23h For the same reason robots do not fold your laundry or sew your clothes. Automated systems do not perform well in environments where everything isnot completely predictable. Because there is no way to predict exactly how clothes will form a pile,and fabric can stretch and fold in any direction, those two simple tasks havebeen two of the hardest things to do with robots. You are under themisconception that the most important thing a pilot does is manipulate thecontrols. Mostpeople can learn how to fly a plane with a few hours of instruction.That part, flying the plane, is the fun part of the job, but it can be, andoften is, managed automatically. The important part of the pilot’s job is judgement and decision making. Sometimes the decisions to make cannot bepredicted or pre-programmed in advance, so they are beyond the capability of anautomated system. Q7 What phone activityconsumes battery fastest?

Choose whole grains like quinoa, brown rice, and whole wheat bread,and lean protein sources like chicken, fish, legumes, and tofu. These foodshelp maintain energy levels and support overall health during hot weather. Spices and herbs: Certain spicesand herbs can help promotecirculation and cooling in the body. Examples include mint, cilantro,coriander, fennel, and cardamom. Incorporate them into your meals to add flavourand potentially provide some cooling effects. Limit heavy, high-fat meals:Heavy, high-fat meals can makeyou feel sluggish and increase metabolic heat production, potentially makingyou more susceptible to heat-related illnesses. opt for lighter, balanced mealsthat include a variety of fresh ingredients. Remember that these dietary tipsshould be combined with other preventive measures to avoid heatstroke, such as staying in coolenvironments, wearing appropriate clothing, and avoiding excessive sun exposureduring hot weather. If you suspect heatstroke or experiencesymptoms like dizziness, rapid heartbeat, confusion, or nausea, seek immediatemedical attention. Q9 Can pilots see otherplanes on radar? A9 Erika Fernandez, Experiencein Aviation Field Sat It is important to note that pilots do not see other planes on radardirectly. Instead, air traffic controllers use radar to trackthe location and altitude of planes in their airspace, and then communicatethis information to pilots through their cockpit instruments and radios. In addition to radar, pilots can also use a system called Traffic Alertand Collision Avoidance System (TCAS) to receive warnings about nearbyaircraft. TCAS uses signals fromother planes to determine their location and altitude, and then alerts thepilots if there is a potential conflict. It is worth noting that while radar and TCAS are effective tools foridentifying and avoiding other aircraft, pilots are still responsiblefor maintaining a visual lookout and using their judgement to ensure safeseparation from other planes. Therefore, they need to keep their eyes and ears open while flying toavoid any potential mid-air collisions. Q10 Is it dangerous to eatbananas and eggs together? A10 Mohd Zeeshan,22h No, it is not dangerous to eat bananas and eggs together.
