Consider a feedback control system with a proportional control strategy. which has the following open loop transfer function, G(s)H(s) : K(s + 2) G(s)H(s) = „K > 0 s(s² + 7.2s + 36)(s – 0.5) Draw the detailed & hand-drawn Root-Locus plot by calculating all necessary and important parameters (the number of branches, the part of real axis that belongs to root locus, ..., angles of departures/arrivals etc.) for drawing. Show all these informations on your plot as well as clearly indicating on branches the directions of increase in K. Determine the range of gain K for a stable system.

Question

This a control system question for mechanical engineering. I dont understand. Also i am sending a second pic for rules of root locus(its for help to you) please help me ? 

Consider a feedback control system with a proportional control strategy. which has the following
open loop transfer function, G(s)H(s) :
K(s + 2)
G(s)H(s) =
„K > 0
s(s² + 7.2s + 36)(s – 0.5)
Draw the detailed & hand-drawn Root-Locus plot by calculating all necessary and important
parameters (the number of branches, the part of real axis that belongs to root locus, ..., angles of
departures/arrivals etc.) for drawing. Show all these informations on your plot as well as clearly
indicating on branches the directions of increase in K.
Determine the range of gain K for a stable system.
