use K>5.0
Thank you
(b) The open-loop transfer function (OLTF) of a unity feedback servomechanism system is given by: K(s + 10) G(s)H(s) = 33 where K is the open-loop gain.

(ii) sketch the Nyquist diagram of the system in the GH(jw)-plane and investigate the system's behaviour for varying Kvalues. [6 marks] (ii) using the results from Part (ii) show that the system is stable for K > 5.F. Validate your answer using the Routh-Hurwitz stability criterion. [4 marks]
