It can be shown that . . .
It can be shown that . . .
Apply Newton's 2nd law to the system:
(1")
- where:
- a is the acceleration of the mass, m.
The forces imposed on the seismic mass are given by:
(2")
(3")
(4")
The acceleration of the accelerometer housing is defined as:
(5")
Substituting into Equation 1":
(6")
which
becomes:
(7")
Dividing Equation 7" by k, yields:
(1)
