Explain the difference between an MMC virtual condition of an external feature of size and an MMC virtual condition of an internal feature of size.
What will be an ideal response?
ANS:
An MMC virtual condition (of an external feature of size) is a constant (worst-case) boundary generated by the collective effects of the largest feature of size (MMC) plus the applicable geometric tolerance.
An MMC virtual condition (of an internal feature of size) is a constant (worst-case) boundary generated by the collective effects of the smallest feature of size (MMC) minus the applicable geometric tolerance.

A dc, separately excited motor has an armature resistance of 1 ? and field constant K? = 3 Vs. The motor is driven by a full-wave, ac/dc, SCR circuit. The triggering angle of the SCRs is 30o . The voltage on the ac side is 277 V (rms). The motor load is bidirectional and equals 120 Nm at steady state, regardless of the direction of rotation. A countercurrent braking is implemented by reversing the polarities of the motor terminals. The triggering angle of the SCRs is adjusted so that the maximum braking current is twice the steady-state value. Calculate the new steady-state speed.
