A shaft has diameter $20^{+0.05}_{-0.15}$ mm and a hole diameter $20^{+0.20}_{-0.10}$ mm. When these are assembled, then what is the nature of fit yield?
A closed-loop system has the characteristic equation given by: $ s^3 + k s^2 + (k+2) s + 3 = 0 $.
For the system to be stable, the value of $ k $ is:
