5. AIR BAGS
An airbag is a type of vehicle
safety device and is an occupant
restraint system. The airbag
module is designed to inflate
extremely rapidly then quickly
deflate during a collision or
impact with a surface or a rapid
sudden deceleration.

7. History and Development
 The first commercial designs were
introduced in passenger automobiles during
the 1970
 General Motors marketed its first airbag
modules under the unwieldy name "Air
Cushion Restraint System (ACRS)".
 controlled by a central Airbag control
unit (ACU), The ACU monitors a number of
related sensors within the vehicle,
including accelerometers, impact sensors,
side (door) pressure sensors, wheel speed
sensors, gyroscopes, brake pressure
sensors, and seat occupancy sensors.

8. Working
 Airbag systems contained a mixture
of sodium azide (NaN3), KNO3, and
SiO2. A typical driver-side airbag
contains approximately 50-80 gm of
NaN3, with the larger passenger-side
airbag containing about 250 gm. Within
about 40 milliseconds of impact, all
these components react in three
separate reactions that produce nitrogen
gas.

28. The Road Not Taken: ROBERT FROST
Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth………..
I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and
I took the one less traveled by,
And that has made all the
difference.
