Question

Find the acceleration of the pulse ​

Answer 1

Explanation:

An accelerometer is a particularly convenient object to

evaluate, since it may directly characterize the amplitude

and pulse width generated from an impact. Many

accelerometers have maximum acceleration ratings

which are sufficient to measure high acceleration levels

in a wide variety of applications. It should be realized

that in almost every case, ratings may be exceeded by

seemingly benign handling shocks.

It has been demonstrated that when dropped from a

height of one meter, objects may impact rigid surfaces

with very large accelerations. Relatively speaking, lower

mass objects tend to result in greater accelerations. As

an example, an accelerometer, with a normal mass of

only 10 grams, may easily be subjected to 30 000 g when

dropped from one meter onto a rigid steel plate. If the

interface on impact is flat-to-flat, the level may exceed 80

000 g.

The amount of acceleration imparted to a dropped object

is proportional to the square root of the drop height, and

the inverse of the pulse width.
