KNOW WHY THERE IS NO REVERSE GEAR IN MOTORBIKES !!

You might have observed that motorbikes do not get reverse gear. Let us discuss the reason behind this in this article.

The front fork of all bikes has an angle and "rake", which assist in keeping it going straight and make it easy to correct balance without falling over. This does not work in reverse very well, as the rear wheel is fixed. You can train yourself to ride backwards, but it is very difficult. In addition, it would be dangerous on a motorcycle and pointless since motorcycles have a tight turning radius and you can simply push it backwards with your feet. They are not used because you can easily push your bike backwards with your feet.

Reverse gear takes up space and adds weight. Space is limited in motorcycle. The bikes transmission is not designed in similar fashion as that of car due to the space restriction.

 

Some heavy touring bikes like Honda GL1800 Goldwing and BMW K1600, which weigh over 375kg each and are difficult to push do have a reverse gear, to assist in getting out of parking spaces only. It uses the starter motor, not the engine, to give it a slow push.

BHARAT BENZ AND MERCEDES BENZ :KNOW THE RELATION !!

Bharat Benz and Mercedes Benz belongs to the German multinational vehicle maker Daimler AG. They are same company in the same sense as to how Jio and Reliance Digital are the same company.

Mercedes Benz is a globally recognized luxury car brand owned by Daimler AG which in 2018 sold the higher luxury car globally. Mercedes Benz cars are also visible across several cities globally. But many people may not know that Daimler AG also sells Mercedes Benz branded trucks and buses too.

Bharat Benz is a solo truck brand  which sells trucks only in India. A little background on Bharat Benz.

India is one of the largest growing economies globally and happens to be one of the largest heavy truck markets, but globally- behind China. Daimler AG is one of the largest truck manufacturers selling its trucks almost all the major market. However, the company wasn’t present in India- which is one of the large truck markets. In 2008, the company announced over Rs 4500 crore investments in India to enter India’s truck market and set-up a manufacturing plant at the outskirts of Chennai.

While the company talked to all the stakeholders, it realized that the truck market in India is tough to crack- to command the customer respect and show its commitment to the Indian market, the company decided to build a local brand instead of bringing its established international brand to India. As part of this strategy, Bharat Benz- a new truck brand first of its kind was unveiled for the first time for any single market globally by Daimler AG.

At the same time, some other global brands such as MAN Trucks- which has shut shop in 2018 and Scania is finding it hard to stay put in India. Gradually, Daimler has been able to make a mark in the market with a reasonable market share, which is growing well. In 2014, the company has introduced Bharat Benz buses too in India.

KNOW WHY SATELLITES ARE WRAPPED IN GOLD COLOURED FOIL !!

You’ve probably noticed that many artificial satellites are covered with what seems to be gold or silver foil. In fact, it’s not just satellites; you can see this in most space-related equipment (i.e., the equipment that actually goes into space).

While they may seem like they are draped in precious metal, it’s usually not gold at all… or even foil! It is actually a material called multi-layer insulation, or MLI.

MLI consists of lightweight reflective films assembled into thin layers that range in thickness. These layers are usually made of polyimide or polyester films (types of plastics) coated with very thin layers of aluminum. This is used over critical spacecraft parts to severely limit effect of surface temperature fluctuations in parts sensitive to thermal changes by limiting the amount of heat transferred between the two sides of the layers.

Depending on its orbit, a satellite can experience temperatures from below -200°F to well above 300°F, sometimes at the same time! Not to mention the high temperatures the onboard instruments can produce.MLI is designed to reflect solar radiation back into space, keeping the instruments cool enough to operate while in sunlight. It also maintains internal temperatures by keeping heat in, protecting the instruments from the extreme cold experienced when the spacecraft moves through Earth’s (or its own) shadow.

MLI can also provide a layer of defense against dust impacts, protecting delicate internal instruments and sensors from tiny particles of space debris.
