Gravity Ferrous Engineer Interview Questions and Answers

The maximum load force in a four high rolling mill can be calculated using the formula: Maximum Load Force = Frictional Force + Rolling Force

• Frictional force is the force required to overcome the friction between the rolls and the metal being rolled.

• Rolling force is the force required to deform the metal being rolled.

• The maximum load force is the sum of the frictional force and the rolling force.

• The frictional force ca...read more

Positive displacement pumps move fluid by trapping a fixed amount and forcing it into the discharge pipe.

• Positive displacement pumps move fluid by trapping a fixed amount and forcing it into the discharge pipe.

• They create a constant flow rate regardless of the system pressure.

• Examples include reciprocating pumps, rotary pumps, and diaphragm pumps.

• Non-positive displacement pumps, like centrifugal pumps, use impellers to...read more

Angular contact ball bearings can handle both axial and radial loads.

• Angular contact ball bearings are designed to handle both axial and radial loads.

• They have a contact angle between the balls and the raceways, allowing them to support axial loads.

• At the same time, they can also support radial loads due to their design.

• These bearings are commonly used in applications where both types of loads are present, such as in m
