The root locus diagram has loop transfer function G(s)H(s) = K/ s(s+4)(s2+4s+5) has
A. No breakaway points
B. Three real breakaway points
C. Only one breakaway points
D. One real and two complex breakaway points
Answer:B
The root locus diagram has loop transfer function G(s)H(s) = K/ s(s+4)(s2+4s+5) has
A. No breakaway points B. Three real breakaway points C. Only one breakaway points D. One real and two complex breakaway points
Explanation: The breakaway points are the points where the root locus branches break and it is not necessary that this point must lie on the root locus calculated by differentiating the value of K with respect to s and equating it with zero.
