CULTURAL QA 10-2022-10 BEING A COMPILATIONTHERE MAY BE ERRORS
Q1 What are the dangers of touching ahigh tension wire? A1 John Adamson, Retired(2014–present)27m They carry veryhigh voltage. Funnily enough as long as youare not touching anything at a different potential it’s quite safe.Birds sit on them quite Happily. Q2 How is barbed wire dangerous? A2 Loring Chien, Former PrincipalEngineer at Fortune 1000 Company (2002–2016)5y It has sharp pointson it. Every few inches. If you come in contact with it, it is painful and willlikely break your skin or puncture it. That causes cuts, bleeding and possibly infection as the steelused is often rusty and not sterile. Unless you are thedensest person on earth, You learn quickly to avoid it. My note- Above the compound wall Iron bars areerected except in the front in most homes. Recently partially in the frontalso. This avoid some street dogsjumping and creating menace. Also creeping plants like betel, bitter gourd,money plant also are spread on it. Even with best quality barbed wire, rustinghappens, and periodically replaced. However the bars erected to put through fencing wire are painted. Q3 Is a neutral wire more dangerous thana hot wire? A3 Josephine Hollivan, Electrician(2014–present)1y The neutral wire is intended to carry current. Anycurrent-carrying conductor can be dangerous. Electricity is dangerous becauseit is most often an invisible hazard. I suppose it couldbe “more” dangerous because you aren’t typically expecting a neutral to haveactive current on it, and may discount its ability to push current through yourbody. Q4 Which is the best berth to choose inthe 2A class on Indian trains? A4 Raunaq J,A Keen Observer Oct 4 While travellingalone, I think that theside lower birth of 2AC Coach is the best. You can easily setyour luggage below and rest/sleep on the berth and set the curtains-Fullprivacy and 0 disturbance. You also get a big window all for yourself to ponderoutside and enjoy and look at the stations, and obviously you get a chargingsocket and reading light. The seat dimension is maybe to similar to 3AC but it iscomfortable unless you’re too tall or fat. I’m 5′11and never had any issues there. Of course, the main 4 berths are bigger than3AC and more comfortable than the side berths, but I would still opt for thiswhen I’m travelling alone, as the pros outweigh the con. Q5 How did humans get luckyevolution-wise in that we are able to think better than other animals? A5 Claire Jordan, Degree in biology andfolklore; programmer, shop owner, secretary on newspaper20h A combination of factors. First off, apeshave a head start on becoming bipeds with upright bodies (rather thanhorizontal bodies, like most other bipeds), because apes brachiate - that is,swing underneath branches using their arms - so they were already adapted tohaving a vertically-aligned torso and gripping hands. So, about seven million years a go, a nearby supernovaled to an increase in electrical storms, which burned off alot of brushland in Africa and allowed a savannah-type ecosystem to expand. A group of semi-bipedal apessplit in two, with one group moving out onto the plains, while the other moveddeeper into the jungle. The jungle groupevolved to be more quadrupedal because that helped them to get around in dense cover,and became the ancestors ofchimps and bonobos. The plains groupevolved to be more bipedal, because that enabled them to see over the tallgrasses of the savannah, and spot predators and prey from a long distance. Becoming more bipedal freed up theirhands, which no longer had to double as walking feet, and their shoulders,which could now adapt for throwing. With these freer,more nimble hands theystarted to make better tools. They were probably already able tomake very simple wooden and stone tools, because chimps do so, but now theycould begin to shape blades and tie them to a shaft, and devise complex huntingstrategies to use them. Large brains are a two-edged sword because they take a lot of power torun, and in placental mammals they make childbirth more difficult and dangerous.But with dexterous hands and mobile shoulders, it became an advantage to bemore intelligent in order to make better tools, and then with better tools theybecame better hunters. Withmore access to meat and fat they had more energy to maintain ever biggerbrains, especially once they learned how to use fire to cook, sothat set up a positive feedback loop which enabled them to get more and moreintelligent, until theyhit the upper limit of how big-headed human infants could get without eitherkilling the mother, or the mother having to have such a wide pelvis she couldbarely walk, or the infant being born so small and/or premature it couldn’tsurvive. MY note- A lengthyanswer by Mrs Clara. Often she writes short answers. Q6 I have eaten 30 grams of fiber today,but I am unable to have a good bowel movement. Why is this? A6 Victoria Arlington, Studied Nursing(BSRN) at San Francisco State University (SFSU)Thu There are severalreasons why people have trouble with bowel movements. Fiber helps, but really thebigger thing is how much water do you drink in a day? Or things that are closeto water like tea. The average amountpeople need to get down in a day is 8- 8oz. cups. At least. After water, and fiber, comes exercise.You need to move around each day, walking or something to help bowel movements. Finally, whileyou are eating fiber, DON’T eat things that tend to constipate you. Eating a lot of high-fat meats, dairy products and eggs,or rich desserts and sugary sweets may cause constipation. My note- Inspiteof having fibre rich food, drinking water, certain medication createsconstipation. Q7 What are the holes in concrete? A7 Qamar Hayat, Tue Surface voids arethe cavities or little holes that appear on the surface of concrete castings. Surface voids (commonly known aspitting) are referred to as “bug holes” or “fish eyes”. These voidsmay produce an unacceptable appearance on the surface of the finished casting.Understanding the causes of surface voids and what can be done to minimize themis the first step to amore efficient and productive casting operation. Surface voids aregenerally attributed to the following three factors: Releaseagent, Water, Air – sometimes acombination of the three Factors causingsurface voids Releasing Agent Release agents actas a “lubricant” between the mold and the concrete. The proper application of arelease agent will yield castings without surface voids. When a release agentis over applied, it may “pool” or “puddle” on the lower extremities of the moldand when concrete is poured these pools prevent the concrete from filling in100%. Water Similar to releaseagents, water is also trapped against the mold’s working surface resulting invoids. As the concrete cures and the residual water evaporates, a cavity isleft behind on the surface of the casting. However most voids caused by water are a result of ahigh water to cement ratio. AIR In mostcircumstances, air voids have an irregular shape and tend to be much larger(1/2″ or 1.27 cm.) than those caused by water or release agents. The air voids are caused byair trapped between the mold surface and the concrete. Theygenerally appear in low slump concrete and can be found underneath irregular(non-spherical) shaped pieces of crushed aggregate. This is aresult of having too little mortar to fill the spaces around the aggregate. How To Eliminate Voids In A Concrete Casting: While manyvariables must be considered in the elimination of surface voids in concretecastings, there are a number of precautions that can remedy this unsightlyproblem. 1.Make sure that releasing agents are applied in thinfilms. 2.Techniques usedduring compaction can eliminate most surface voids. i) Suitable size of needle virator should be used ii) Concrete shouldbe compacted layer by layer iii) Needle shouldnot touch reinforcement and formwork 3. Tapping the mold with rubber hammer / wooden hammercan eliminate any residual voids. Q8 Howcan water damage be prevented on a washing machine? A8 Gopala Krishnan, Former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966–2004)Just now A spindle is available in Chennai, Tamilnadu market whichhas metal ends with holes on either sides. One end isconnected to machine and another to water inlet. When purchased and connected it’s colour is white.While absorbing impurities, it’s colour gradually changes to brown. This spindle cost 2000–00 rupeesin Chennai. It’s life span is about 2 years. I have connectedone about 4 months back to my automatic washing machine. How that small spindle works (technically) for TWO years is not clearto me. Such spindlelarger in size was fitted to a stainless steel water container in the centreand provided with a tap was earliest water purifiers in Tamilnadu during1981’s Q9 Is it necessary to keep our watertanks full of water? A9 Gopala Krishnan, Former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966–2004)Just now In the early yearsof construction of home, fillingfull tank can indicate leakage if any and prove the water holding capacity without any damage to walls. Later period, itis mental satisfaction, confidence , the family has full tank of water inreserve. Further dustand clay from bore wells will settle at bottom, full tank water will keep themdown below the outlet to certain extent. Q10 What is the benefit of booking a roomwith a balcony on a cruise ship? A10 Dave McGlade, Lives in The UnitedKingdom Oct 3 We book a balconyaround half the time and “ocean view’ (window) about the other half. A few oddexceptions, but that's the norm. The balcony gives more space, typically (not alwaysthough) and if the climate is suitable, it is apleasant place to sit and relax. If you are a “fresh air fiend’ it is farbetter than the air conditioning. You can often get a great view of the portsboth as you arrive and when docked. But I would alsotake the itinerary into account. The trip after next is to Iceland. A lovelycountry, but I would not spend much time. on the balcony, so that is an oceanview.
