A spring oscillator is designed with a mass of 0.1480.148 kg. It operates while immersed in a damping fluid, selected so that the oscillation amplitude will decrease to 1.00% of its initial value in 5.845.84 s. Find the required damping constant for the system.
Homework Answers
A = A0 e(-lt)
0.01=e(-l*5.84)
ln100=5.84*l
l=0.7885
we know that l=b/2m
so b=2ml
damping constant = 2ml = 2*0.148*0.7885 = 0.2153 kg/sec Answer
feel free to drop comment if you have any doubt.
