Q3. What is the Vernier least count
Ans. 
Vernier least count is the smallest measurement that can be made using a Vernier caliper or scale.
• It is the difference between the smallest division on the main scale and the smallest division on the Vernier scale.

• It is used to measure the accuracy of the instrument.

• For example, if the main scale has divisions of 1 mm and the Vernier scale has divisions of 0.1 mm, the least count would be 0.1 mm.

Q1. How to calculate work roll bearing BEP
Ans. 
The work roll bearing BEP can be calculated using the formula BEP = (0.5 x (F1 + F2) x L) / (F1 - F2)
• BEP stands for Bearing End Play

• F1 is the force on the roll due to the strip

• F2 is the force on the roll due to the backup bearings

• L is the length of the bearing

• The formula assumes that the forces are evenly distributed across the bearing
