Question

Which of the following has the most magnitude?

(a) Slip velocity

(b) Surface velocity

(c) Entering velocity

(d) Exiting velocity

This question was addressed to me by my college professor while I was bunking the class.

This interesting question is from Flat Rolling topic in portion Forming Process of Casting-Forming-Welding II

Answer 1

Right answer is (d) Exiting velocity

The best I can explain: Exiting velocity, among the given four velocities, that is slip velocity, surface velocity, entering velocity and exiting velocity, the exiting velocity is considered to be having most magnitude.
