  1. While rolling a strip the peripheral velocity of the roll is.... A.... than the entry velocity of the strip and is... B... the exit velocity of the strip.
    1. less than/greater than
    2. greater than/less than/equal to
    3. less than
    4. greater than
Correct Option: A

At entry, plate velocity is smaller than Roll velocity then it increases & becomes equal to roll velocity at Neutral plane after that it is higher than the roll velocity.
