KNOW THE FUNCTION OF LINES ON REAR WINDSHIELD !!

You have probably noticed the lines on the rear windshield of your vehicle.Have you ever wondered what those thin lines running across the length of your rear window are for? We will discuss about these lines in this post.

These lines are called defoggers. These lines are electrified filaments which dissipate heat in the case your rear windows begins to fog up.A small current is passed through those embedded wires or lines, and as the current is conducted, it heats up the glass slightly—just enough to melt any snow or ice blocking your view, or eliminating any fog/condensation that was built up.Your front windshield comes equipped with defoggers, too. But since driving with a bunch of thin lines obstructing your view probably isn't ideal, it instead comes in the form of vents near the base of the glass.

All of these small details on a car may not seem to add up to much, but they are integral to the safety and comfort of the passengers, as well as the structural integrity of the vehicle itself. Next time you sit down for a long drive, pay attention to those tiny details and be grateful that someone in the car manufacturing industry thinks about the small stuff!

DIFFERENCE BETWEEN FORCE AND PRESSURE EXPLAINED !!

Force and Pressure are the two important concepts of physics which are often erroneously interchanged by the people. But, these two are not same at all, as there is a vast difference between force and pressure,we will discuss about the difference between them in this post.

FORCE:

Force is the pull or push on an object which can change the velocity of the object on which it is applied. We can say that if force is applied on an object from one direction and there is no opposing force, then the object will move. If it’s already moving, it will either get faster or slower depending upon the direction of the applied force.

PRESSURE:

Pressure can be explained as force applied on a unit area.When the force is applied over a large area, then the pressure developed.

Now have you ever wondered, why tools which are made to cut, chop, trim or pierce always have sharp edges? Or why heavy vehicles always have fat tyres? This is only due to pressure, which refers to the physical force per unit area.

The difference between force and pressure is summarized in the table given below:

 

WHY SMALLER WHEELS ARE USED IN SCOOTERS ?? KNOW HERE !!

Scooters are often used as a way to get around that’s both good on fuel as well as easy on the pocket. They generally weight less than motorcycles but are also slower. However, the type of wheels that you have on a scooter, whether they’re big or small, can make a lot of difference.

More common these days are that scooters are getting 12” and 13” inch wheels. So what is the advantage? 

Using small tyres in a scooter provides additional space between the seat and tyre, where you can mount the engine and transmission. Because of small size only, this space is available. Hence the scooter is compact, has under seat storage and space at front for keeping your legs and goods.

Also, small wheels and tyres helps in incredibly quick steering. But again it leads to poor handling at higher speed.

So,the main reason for giving smaller wheels to scooters is to reduce the weight of the vehicle, increase the space requirement, and to offer a great manuvarity in city traffic.When it comes to poor handling at higher speed, scooters are not designed to run at high speed that is why smaller wheels are provided.
