Question

The seismic mass of an accelerometer oscillates sinusoidally at 100 Hz with a maximum displacement of 10 mm from its mean position. The peak acceleration of the seismic mass is

• A. $3947.84m/s^2$
• B. $3141.50m/s^2$
• C. $314.15m/s^2$
• D. $100.00m/s^2$

Answer 1

The correct option is A $3947.84m/s^2$

$\text{Peak acceleration =}{\omega }^2{x}_m$

$=(2\pi \times 100{)}^2\times 10\times {10}^{-3}=3947.84m/s^2$
