Q. The system 2d2y/dt2+4dy/dt+8y=8x, has damping ratio______ a. 0.25 b. 0.1 c. 0.33 d. 0.5 Answer and Explanation Answer is 0.5 The given System is a second order system and is given by 2d2y/dt2+4dy/dt+8y=8x After taking the Laplace Transform we get 2s2Y(s)+4sY(s)+8Y(s)=8X(s) or (2s2+4s+8) Y(s)=8X(s) Y(s)/X(s) =8/(2s2+4s+8) so, the transfer function of the system is…
