Answer:
Check the explanation
Explanation:
To write the closed-loop transfer function for the system and determine the closed-loop pole locations as well as to determine the damping ratio and the natural frequency, we will be be doing a step by step calculation and explanation including the graphical presentation as seen in the attached images below.
Answer:
Stress-concentration
In the machine component the stress become concentrate at the point a particular point and due to this crack formation takes places and after some time some the machine component become fails.High stress concentration means high stress at that point.
It is very important in the design point of view because we have to find out where stress concentration is high and needs to take proper factor of safety to avoid the failure of the machine component.Generally at sharp corner,sudden change and complex shapes stress concentration is high.
