CULTURAL QA 11202315A
Q1 Why do planes stop before take-off?
KR Hoodwinking learnt celebrity for the compiler. Any Plane can
take off in one stroke; need not halt; but certain routine procedural
instructions only compel the pilot to halt. No more even in Gossip Q and A
some reels.
Q2 What makes Indian moms happy?
KR Why are moms and not all ladies? And why not earth moms or
ladies? Lethargic males are there but never any lady.
Q3 What would happen if the Earth abruptly stopped spinning for 42
seconds?
KR Mr G gets wild and relies on some as so learnt for throwing
imaginary Q and A which is not scientifically registered; in FAQ and some
joke-interviews, it is told in that manner. Such things are not found in
encyclopaedia as no one teaches the posterity, things of which they are not
sure. If it is passing for time, it is oK; but suppose a young 23 goes for
an interview and answers like this, well when he is turned off, only G is
to be blamed along with the learnt.
Basically, why are there is revolutions? Unless there is a force
acting on a point…..sound read somewhere in physics? The Sun's gravity
pulls the planets in orbit around it, and some planets pull moons in orbit
around them. Even spacecraft are in motion through the solar system, either
in orbit around the Earth or Moon, or traveling to further worlds, because
of gravitational forces.
And why is there gravity akarshana? Earth's gravity comes from all
its mass. All its mass makes a combined gravitational pull on all the mass
in your body. That's what gives you weight. And if you were on a planet
with less mass than Earth, you would weigh less than you do here. Have you
seen the science words used very carefully? Earth’s. Because there might be
a place of no gravity where there are no movements also. So only where
there is a mass there is powerful pulling the less powerful. So once there
a force acting on a point revolution starts unending. So if something must
stop moving, the mass must become zero; the greater and less one who have
no mass, cannot be gravities; so it shall halt. If there is no mass, then
alone it will stop. Then where is the question of holding water etc to be
thrown off? If mass is zero, none will be thrown off. Also, every object by
deceleration only can stop; that is 42 sec assumed as a car or motorcycle
speed reductions are considered. Similarly, as in accident we are thrown
off, the throw off theory was conceived. But only without a mass gravity
will fail and so stop; if so, what will be thrown off? SUN is believed to
be by certain theory as not rotating by itself which is not science.
Q4 Why are petrol tankers elliptical in shape?
KR L: One of the main reasons why petrol tankers are elliptical in
shape is to lower the center of gravity of the vehicle. G: My note-
Further to reduce centre of gravity and more control, the elliptical tank
is divided into three in most oil tankers. {L=learnt}
Before the elliptical, what about 8 wheelers carrying tall
containers in height running a long distance at high speed? All vehicles
are designed only wrt the COG. The centre of gravity (COG) of the
human body is a hypothetical point around which the force of gravity
appears to act. It is point at which the combined mass of the body appears
to be concentrated. Whether compartmentalised or not, (G) COG is that
point of acting through.
NASA release:
[image: image.png]
[image: Computer drawing of a variety of objects showing the center of
gravity - CG. CG = sum of component weight times component distance divided
by total weight.]
So many shapes can be there but the mass must act only
through the CG point which is important. So elliptical is not a criteria.
So compartmentalising is not for CG. Liquid occupies the shape in which it
is stored; and liquid filling needs deep cleaning. The liquid has a
tendency to pour into crevices and holes and might get sponged up also. So
where there is skidding the quantum might stay put. And curvature cleaning
is easier. Compartment is saving grace in case of loss; and easy filling ;
and the impact inside is minimised so that vehicles do not sway.
Q5 What are some unwritten social rules everyone should know?
KR: If it is unwritten, why would it matter as unwritten might be
written for the sake of a few also.
1. 1+1 = 3 if you don’t use the condom.
KR Condom is only a preventive measure where X and Y will burn
together; where there is nothing like that it is as good as with or
without. So, 1+1 is not equal to 3 always; so not a universal truth. So,
it is written; and unwritten for the half baked only.
2. Alcohol increased the size of the “SEND” button by 89%.
KR The problem of the learner and the compiler not to know what
it means and branded in the world as hippie life, Fun fact And means
nothing as unquoted rule. Show me any idea configured anywhere.
3. Never underestimate the power of stupid people in large groups.
KR True 1 or 10 or 100 or 1000 or infinity would make only one power
of stupid and because it is volume never reduces below zero to one or below
zero.
4. Sometimes we create our own heartbreaks through expectations.
KR Is it a rule recently invented? Bhaja govindam speaks from our
ancient philosophy. Old wine in a new bottle?
5. Life is too short to be with the wrong person.
KR BUT VERY FAIR SINCE THE NEXT ONE CANNOT BE FOUND AS A RIGHT
PERSON TOO. SO LIFE IS SHORT TO KEEP ON HUNTING.
6. Just because you love them, it doesn’t mean they’re right for you.
KR If loved ones really are no right kinds then love is wrong
7. Feelings that come back are feelings that never left.
KR Then the feeling of comeback is a lie?
8. Everything’s not as easy as getting fat.
KR Wrong deduction; getting fattier is not that easy unless your
constitution is framed like that. There are people who eat a lot but
without fitness exercise stay lean.
9. Even a bad day is just 24 hours.
KR Of course day has only 24 hrs; but good or bad is yours and not that
of the day. Bad day means the day is bad; hot sun or flooded one etc
10. It’s not your job to fix people.
KR THAT IS WHAT VESTED INTERESTS ARE TELLING ABOUT BUT BUDDHAS,
SANKARAS ARE BORN ONLY HERE WHO DID NOT THINK SO.

Q1 Why do planes stop before takeoff?
A1 Vishnu Ravi, Aerospace Engineer | Aviation Enthusiast & Content
Creator Aug 1
When it comes to ensuring a safe and smooth flight, stopping before
take-off is crucial for several compelling reasons:
Configuration: Before embarking on their journey, planes make a momentary
stop to configure flaps. These movable wing surfaces play a vital role in
generating the lift needed during take-off, ensuring a seamless departure.
Clearance and Communication: The expertise of a skilled pilot extends
beyond just maneuvering the aircraft. They need to obtain clearance from
air traffic controllers and engage in essential radio communications with
the destination. This meticulous process guarantees that all flight paths
are secure and coordinated.
Safety Checks: Your safety is our priority, which is why we conduct
rigorous safety checks before take-off. Particularly for piston engines, we
run them at high power to detect any potential issues that might hinder a
safe journey.
Emergency Preparedness: In any unforeseen emergency, your experienced pilot
remains vigilant and prepared. Whether it's engine failure, adverse weather
conditions, loss of control, or technical malfunctions, they can promptly
abort take-off and apply the brakes to ensure your safety.
V1 Speed: The decision to proceed with take-off or abort is influenced by
the V1 speed, the maximum speed at which take-off can still be safely
aborted. Before reaching this critical point, the pilot has full control to
make the right call.
Not Every Plane Stops: I acknowledge that not all planes require a complete
stop before take-off. Rolling take-offs are common, where clearance is
obtained while the plane is already aligned with the runway, allowing for a
smooth and continuous departure.
The Runway's Role: The length of the runway is a pivotal factor for most
planes to gain sufficient speed for lift to overpower the force of weight,
allowing for a successful take-off.
In conclusion, the brief pause before take-off allows pilots to configure
flaps, communicate effectively, ensure safety, and be prepared for
emergencies. Trust in our experienced pilots, as they make well-informed
decisions based on V1 speed and potential issues to prioritize your safety
and deliver an unparalleled flight experience.

Q3 What would happen if the Earth abruptly stopped spinning for 42
seconds?
A3 Aamir Cheema, Faculty member at Monash university Australia,
research interests in computer science Updated 7y
For a start, earth is not spinning. If it is everything including water
will be thrown off.
This answer assumes that the earth stops suddenly for 42 seconds and then
starts spinning at its normal speed.
1. If the earth stops spinning suddenly, the atmosphere will continue to
spin. This means very high speed winds, i.e., approximately 1670 Km/hr
which is earth's rotational velocity. The winds will also cause erosion to
the earth's crust.
2. A sudden stop of the spin will have a similar effect to when you press
brakes on a moving car. You guessed it right, you (and every other object
on this earth) will fly with a speed of earth's rotational velocity, around
1670 km/hr. This is a very high speed but not enough to launch the objects
in space, so no space trip for any of us.
3. The earth will become a perfect sphere because the bulge in the earth is
due to its rotation. This bulge is along the equator and the oceans as they
are now are due to this bulge. If there is no bulge and the earth is a
perfect sphere, the oceans will redistribute resulting in one massive
supercontinent that circles the equator and the north and south poles will
become oceans. See the image below:
But since the earth will stop spinning only for 42 seconds the bulge will
not completely disappear before the earth starts spinning again. However,
the effect will be enough to cause flooding (in fact, gigantic tsunami) but
only for 42 seconds after which the bulge will reappear and the flooding
will retreat (causing more havoc).
4. You will have a day 42 seconds longer.
Edit: Thanks Pieter-Paul Kramer and Malakai Lasol Morgan for the comments
that helped to improve the answer.
Q4 Why are petrol tankers elliptical in shape?
A4 Rebecca Williams, Car Lover Nov 9
Petrol tankers are elliptical in shape because of several reasons related
to stability, safety, and efficiency. Petrol tankers are vehicles that
transport liquid fuel from one place to another.
They have to deal with various challenges such as road conditions, traffic,
weather, and regulations. The shape of the tankers is very important to
ensure a smooth and successful operation.
One of the main reasons why petrol tankers are elliptical in shape is to
lower the center of gravity of the vehicle. The center of gravity is the
point where the weight of the vehicle is balanced. The lower the center of
gravity, the more stable the vehicle is. This is especially important for
petrol tankers because they carry a large amount of liquid that can shift
and slosh inside the tank, creating a lateral force that can cause the
vehicle to tip over or lose control. An elliptical shape reduces the height
of the tank, which in turn lowers the center of gravity and increases the
stability of the vehicle.
To maximize the volume of the tank while keeping the height under a certain
limit. Petrol tankers have to comply with the regulations and standards of
the road authorities, which specify the maximum dimensions and weight of
the vehicles. The height of the vehicle is one of the critical factors
because it affects the clearance under bridges, tunnels, and overhead wires.
An elliptical shape allows the tank to have a larger volume than a circular
or rectangular shape while keeping the height within the permissible range.
This means that the petrol tanker can carry more fuel with less trips,
saving time and money.
To improve the aerodynamics and fuel efficiency of the vehicle.
Aerodynamics is the study of how air flows around objects and affects their
motion. Fuel efficiency is the measure of how much fuel is consumed by the
vehicle per unit of distance. Both of these factors are influenced by the
shape of the vehicle, which determines the amount of drag or resistance
that the air exerts on the vehicle. Drag reduces the speed and increases
the fuel consumption of the vehicle.
An elliptical shape reduces the drag by having a smooth and streamlined
surface that minimizes the turbulence and pressure difference caused by the
airflow. This means that the petrol tanker can travel faster and use less
fuel, reducing the environmental impact and operational cost.
My note- Further to reduce centre of gravity and more control, the
elliptical tank is divided in to three in most oil tankers.
