Beautiful spring！ And…. bang
As we talk about it last week, we talk
OK, so a lot of people want to know why their car’s window(which was totally fine yesterday) suddenly broken down in spring morning. But the first thing is answer what the glass is.
Un.. Glass of your car’s front window is not the normal glass like your room’s. The window we used on your car’s window
There’re two main reason why this safety glass failure. First is the glass itself….Secondly is what we want talk today, so called as the structure damage. When you have structure damage on the glass the
Another question is: the dent.
The dent is not just dent. Have you ever seen the bubble in the air. It seems that the bubble is strong and shining like an ballon. But when you touch it, the bubble booms quickly. The force which hold the surface called : surface tension,that is we all know on the high school. But this tension is fragile. When you got dent on the galss, just like you stick the bubble. This surface tension will be corrupt because the”surface” didn’t exist in this kind situation. So what the force will go? All the inbalanced force will goes into the dent area. The area of dent or the scratch will be extremely fragile. And ,we can not ignore the problem of the temperature. When the temperature changes, the inside and out side air pressure will be different. All of these above like a hammer in on the window. so when you driving on the road at the speed of about 70 or 75 mp your window could broken suddenly! At first, sure the structure failure will cause some crack.Then the crack will grow fast at the speed you can see. Finally the glass would like a spider’s net. It will not kill you directly, but your sight will be blocked and this will cause accident.
So what we should do now.
First think you can do is so simple which called “Buy the insurance.” AAA, progressive and GEICO provide glass insurance which is not expensive. Only costs several bulks per week you can enjoy the free meal of change class. It seems that most of people only but the basic insurance.
And buy the way. Don’t wait there until the crack come to your car. When you have big dent on glass, check it frequently and observe them to see if it is serous or not. If you have big dent,or crack. DO NO Hesitant, change it right now.
