Problem $(2\mathrm{.}10).$ A motor$-$load system has the following details: Quadrants i and ii$,$ T$=4000\mathrm{.}4$N$,$ N$.$M where N is the speed in rpm$.$ Motor is coupled to an active load torque TL$=\backslash$pm $200$ N$-$M$.$ Calculate the motor speeds for motoring and braking operations in the forward direction. When operating in quadrants iii & iv$,$ T $=-4000\mathrm{.}4$N$,$ N$-$M$.$ Calculate the equilibrium speed in Quadrant iii.
