In _________ machines, the size of the shaft is decided by the critical speed which depends on the deflection of the shaft?

Correct answer: C. large

A. small
B. medium
C. large
D. any of the above.

Explanation

In large machines, the shaft is relatively long and flexible, so its deflection and critical speed become important design considerations. Small and medium machines are less commonly governed by this limitation.
