1. SDOF Systems Governing Equation m(dx^2/dt^2) + c(dx/dt)+ kx = F(t) how do i get this equation below? Free Critically damped Vibration x(t) = e^(wt) [x(0)(1+wt) + (dx/dt)(0) t] (dx/dt is x with 1 dash on top)

centrifugal was for hydraulics if i remember right..so i think it might be centripital..

Very well said..! could you recommend a book for structural engineers that has explanations simple and easy like yours? (american books) have you published any? i have Dunamics of structural systems (Boswell and C'D'Mello) but it doesn't explain in details. Thank you.
