  • We know that AC isn’t just about making coldness, it can be used to make a room hot too because it is a Air conditioning. You can also use an AC as an improvised heater by turning it backwards, so it blows colder air out and hot air in but that would be far from efficient.
  • We know the reason behind the air conditioning system in ICU room is not just for luxury hospital but to host benefit for patients and doctors too.
  • We know the reason behind why airplane windows always have round edges instead of square because sharp corner of square window is weakened by stress concentration.
  • We know “why are tyres in black color ?” because of chemical compound carbon black is added in rubber which increases the strength and durability of tyres and carbon maintains the quality of tyres by protecting them from UV lights and ozone.
  • We know “why are there stones alongside railway tracks ?” – The crushed stones are what are known as ballast. Their purpose is to hold the wooden cross ties in place, which in turn hold the rail in place. It is used to bear load from the rail road ties, to facilitate drainage of water & also to keep down vegetation that might interfere with the track.
  • We know “why do some tuned car have very inclined tires ?” – The tilt of the wheel is know as camber angle. Tilting the wheel in that manner ( as shown in pic) is called negative camber. Mounting the wheel with a negative camber improves grip under hard cornering as it counteracts rolling.
  • We also know “what does the green zone in speedometer indicate ?” – It is the zone where you will have more efficient speed where the fuel consumption is low.
