Ashok Leyland Production Planning Control Engineer Interview Questions, Process, and Tips

Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.

• States that as the speed of a fluid increases, its pressure decreases

• Used to explain lift in airplane wings

• Applies to the flow of liquids and gases

Thermodynamics is the study of energy and its transformations in physical systems. There are four laws of thermodynamics.

• First law of thermodynamics: Energy cannot be created or destroyed, only transferred or converted. Example: A car engine converting fuel into mechanical energy.

• Second law of thermodynamics: The total entropy of an isolated system can never decrease over time. Example: Heat flowing from a hot object t...read more

Case hardening is a process of hardening the surface of a metal while leaving the interior soft, while carburizing is a process of introducing carbon into the surface of a metal to increase its hardness.

• Case hardening involves heating the metal in the presence of a carbon-rich environment, followed by quenching to harden the surface.

• Carburizing involves introducing carbon into the surface of the metal through diffusion...read more

Iron-carbon diagram is a graphical representation of the phases that form in iron-carbon alloys as a function of temperature and carbon content.

• Shows the phases that form in iron-carbon alloys at different temperatures and carbon contents

• Consists of regions for austenite, ferrite, cementite, and pearlite

• Helps in understanding the microstructure and properties of steel

• Used in heat treatment processes to control the fina
