Mechanical Engineering QUESTION #2382
Question 1
The poles of a transfer function \(Y_1(s)\) are defined as:
  • The roots of the numerator polynomial \(Q(s)\)
  • The roots of the denominator polynomial \(R(s)\) when set to zero: \(R(s)=0\)✔️
  • The coefficients of the characteristic equation
  • The gain constants of the system
Correct Answer Explanation
Poles are the roots of the denominator \(R(s)=0\) of the transfer function \(Y_1(s)=Q(s)/R(s)\). They determine the transient response characteristics. Zeros are the roots of the numerator \(Q(s)=0\).
