Mechanical Engineering QUESTION #2381
Question 1
For elements connected in CASCADE (series), the overall transfer function is:
  • \(Y(s) = Y_1(s) + Y_2(s)\)
  • \(Y(s) = Y_1(s) / Y_2(s)\)
  • \(Y(s) = Y_1(s) \cdot Y_2(s)\)✔️
  • \(Y(s) = Y_1(s) - Y_2(s)\)
Correct Answer Explanation
For cascade (series) connection: the output of the first element is the input to the second, giving \(Y(s)=Y_1(s)\cdot Y_2(s)\). For parallel connection: \(Y(s)=Y_1(s)+Y_2(s)\).
