I would ike to tell about Roof power test
A huge number of individuals are killed each year in rollovers. The simplest way to stop these fatalities would be to keep cars from rolling over to begin with. Electronic security control is considerably reducing rollovers, especially fatal single-vehicle ones. Whenever vehicles do roll, side curtain airbags assist protect individuals in, and gear use is vital.

More powerful roofs can also avoid occupants, specially those people who aren’t utilizing security belts, from being ejected through windows, windshields or doors which have broken or exposed due to the fact roof has deformed.
The strength of the roof is determined by pushing an angled metal plate down on one side of the roof at a slow but constant speed and measuring the force required to crush the roof in the test. The force used in accordance with the car’s weight is recognized as the ratio that is strength-to-weight. The peak strength-to-weight ratio recorded whenever you want prior to the roof is crushed 5 ins is key measurement of roof strength. (más…)
