According to D' Alembert's principle, m (d 2 x/ dt 2 ) + c (dx/dt) + Kx =0 is the A
differential equation for damped free vibrations having single degree of freedom.
What will be the solution to this differential equation if the system is critically
damped?
( A ) x = (A + Bt) e – ωt (B)x = X e – ξωt (sin ω d t + Φ)
(C)x = (A – Bt) e – ωt ( D )x = X e – ξωt (cos ω d t + Φ
