COMMON DIFFERENCE EXPLAINED !!

DIFFERENCE BETWEEN RESUME AND CV:

A curriculum vitae (CV) provides a summary of your experience and skills. Typically, CVs for entry-level candidates are longer than resumes – at least two or three pages. CVs for mid-level candidates who have amassed numerous publications tend to run much longer. CVs are thus lengthier than resumes, and include more information, particularly details related to one’s academic and research background.

A resume provides a summary of your education, work history, credentials, and other accomplishments and skills. There are also optional sections, including a resume objective and career summary statement. A resume should be as concise as possible. Typically, a resume is one page long, although sometimes it can be as long as two pages.

DIFFERENCE BETWEEN GUARANTEE AND WARRANTY: 

Guarantee is a commitment made by the manufacturer to the buyer. Just like a guarantor stands behind a loan, the manufacturer stands behind the product. If a product under guarantee is of low quality, it will be either repaired/replaced, or the money paid will be refunded to the buyer.

Warranty is an assurance given by the manufacturers to buyers, that if the product breaks or if there is any problem with the product, the manufacturer will repair the product for free.

DIFFERENCE BETWEEN WATER RESISTANT,WATER REPELLENT AND WATER PROOF:

Water-resistant, this is the lowest level of water protection of the three. If a device is labeled as water-resistant it means that the device itself may be built in such a way that it is more difficult for water to get inside of it, or possibly that it is coated with a very light substance that helps improve the device’s chances of surviving an encounter with water. Water-resistant is something you see commonly among watches, giving it the power to withstand the average hand-washing or light rain shower.

Water-repellent, which is basically just a step up from water-resistant. If a device is labeled as water-repellent it actually possesses the properties in which to, you guessed it, repel water from it, making it hydrophobic. A water-repellent device stands a very high chance of being coated with some form of thin-film nanotechnology, whether that is on the inside, outside, or both, and has a much better chance of standing up to water than your average device. Many companies claim water-repellency, but the term is heavily debated because of all the questions and unpredictable elements associated with it.

Waterproof, on the other hand, describes materials or products that can stand complete submersion without taking in any amount of water. They are suitable for camping, swimming, snowboarding, diving, and many more activities since they can be waterproof to great water depths for a long time. The nature of a waterproof product or material is that it is made with absolutely no holes or pores that might let in water. These products are specifically made for use in environments that have plenty of water. However, on the market today, there are a lot of products that are labeled waterproof but aren’t really waterproof – especially electronic devices. This is especially so because different products have different ‘scales’ or ‘levels’ that determine what should be labeled as waterproof or water-resistant.

KNOW WHY OFF ROAD MOTORBIKES HAVE SPOKE WHEELS !!

You might have seen most of the adventure motorbike uses spoke wheels instead of alloy wheels.We will discuss about the reason in this article.

There are two types of wheels you’ll see with modern motorcycle: wire-spoked wheels and alloy wheels.From first commercial motorcycles in the early-1900s up until about the late-’60s, wire-spoke wheels were majorly used.Then we shifted to alloy wheels and now a days a major portion of manufacturers are using alloy wheels.But still you will see most of the bikes use spoked wheels.They come under the category of Adventure Bikes such as Royal Enfield Himalayan,Trimph Tiger,Hero Xpulse,BMW R 1250 GS etc.

Spoked wheels are all but mandatory on off-road bikes — dirt bikes, enduros, scramblers and ADVS — for one simple reason: spoked wheels are more durable than single piece cast wheels. On the road, while riding around on your street bike, you (hopefully) don’t encounter large rocks or massive ruts — maybe the occasional pothole,but these are adventure bikes are made for rough terrains where alloy may bend.Once alloy is bend it can't regain its shape whereas spoked wheels can bend and flex to a certain degree letting you tackle the rougher terrain.Also these spokes increase the torsional strength of the wheel.The number of times a spoke crosses other spokes on the same side increases torsional strength.

In short,adventure bikes are made for rough terrains wherein they require a wheel that can be ductile and this is fulfilled by spoke wheels.The spokes of spoke wheel take major portion of shock and prevents the deformation of wheel.

KNOW WHY STONES ARE NOT LAID ON METRO TRACK UNLIKE OTHER TRACKS !!

 

You might have observed that stones are laid beside railway tracks but when it comes to metro tracks,there are no stones laid near the track.We will discuss the reason for this in this article.

Let us first discuss why stones are placed near the railway track.The crushed stones you see alongside railroad tracks are what is known as ballast. Track ballast is packed between the sleepers, in the areas below, and on the sides of railway tracks. A railway sleeper is a rectangular support that is usually kept perpendicular to the tracks. The ballast distributes the load of the sleepers (which in turn bear the load of the train on the track, held by clips) across the foundation, allows for ground movement, thermal expansion and weight variance, allows rain and snow to drain through the track, and prevent the growth of vegetation that would quickly take over the track.

When it comes to metro track,it uses ballastless track.Ballastless tracks have different designs to absorb the vibration.They have high initial costs but less maintenance costs. That is why their whole life cost is lower than ballasted tracks. 

 
Since the metro tracks are elevated, drainage and growth of vegetation aren't much of an issue, and the solid structure are designed to bear the wheel loads, and transmit them safely to the earth, there is no requirement of using ballast underneath the track.

There are safety & maintenance issues as well for using ballasts on the elevated sections, as they do pose the risk of flying off and hitting people using the space in the vicinity of the viaducts.
Another reason is that speed is very limited in metro as stations are very close ,that is why impact load is less (for which ballast is used).

Why Railways use ballasted track?

1.Ballasted track is good in the normal speed railway and fast speed railway.

2.Ballasted track requires low investment cost.

3. Ballasted track is usually easy to lay.

4.Ballasted track has good drainage performance.

5.Non-ballasted track cannot be laid in some area like clay deep cutting.

Nevertheless, whenever Rapid transit systems run on the ground, they use traditional methods of load distribution involving sleepers and track ballasts because they are much economic as compared to constructing reinforced concrete girders at places where the latter are not required. Such examples can also be found in Delhi Metro. At sections near Yamuna bank station on blue line, Delhi Metro runs on the ground and uses traditional track ballast.

KNOW WHY POINTED STONES ARE PLACED ON RAILWAY TRACKS !!

Traveling by train is an amazing experience in itself. You get an amazing view of nature. One more thing that you almost always see throughout your train-journey are those small stones lying alongside the track on which your train races?

Have you ever given any thought as to why there are almost always stones alongside a railway track? We will discuss the reason behind this in this article.

The crushed stones you see alongside railroad tracks are what is known as ballast. Track ballast is packed between the sleepers, in the areas below, and on the sides of railway tracks. A railway sleeper is a rectangular support that is usually kept perpendicular to the tracks. These are usually made of wood or pre-stressed concrete, although the latter is more widely used today. The function of railway sleepers is to hold the rails upright and properly spaced. In short, their purpose is to hold the sleeper ties in place, which in turn hold the rails in place.

The rail track is subjected to heat expansion and contraction, ground movement and vibration, precipitation build-up from rough weather, and plant growth from underneath. The ballast distributes the load of the sleepers (which in turn bear the load of the train on the track, held by clips) across the foundation, allows for ground movement, thermal expansion and weight variance, allows rain and snow to drain through the track, and prevent the growth of vegetation that would quickly take over the track.

WHY CRUSHED POINTED STONES ARE USED??

If you put smooth, round pebbles in the ballast, then they might roll or slide over each other when a train passes over the tracks; therefore, they would fail at their main job – providing solidarity to the tracks. Given that fact, you need stones of a specific type that won’t move around too much, except by kids chucking stones near the tracks, of course!

In order to guarantee that the stones stay in place, they use sharp and edged stones in the ballast.

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.
