Stress is the force applied to a material, while strain is the resulting deformation or change in shape.
Stress is a measure of the internal forces within a material that resist deformation.
Strain is the measure of the amount of deformation or change in shape that occurs due to stress.
Stress and strain are related through the material's elastic properties.
For example, when a rubber band is stretched, stress is applied t...
Newton's 3 laws of motion describe the relationship between an object and the forces acting upon it.
First law: An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by an external force.
Second law: The acceleration of an object is directly proportional to the force applied to it, and inversely proportional to its mass.
Third law: For every action, ...

I was interviewed in Aug 2024.
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease voltage levels in electrical circuits.
They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core made of iron or other magnetic materials.
Step-up transformers increase voltage levels, while step-down tr...
Tan Delta testing is a diagnostic test used to measure the insulation quality of electrical equipment.
Tan Delta testing measures the power factor of insulation materials to detect any defects or deterioration.
It helps in identifying potential issues before they lead to equipment failure or breakdown.
The test involves applying a voltage to the insulation and measuring the current flowing through it.
Results are compared ...

A merger is when two companies combine to form a new entity, typically to increase market share or efficiency.
A merger involves two companies agreeing to join forces and operate as a single entity.
The goal of a merger is often to increase market share, expand into new markets, or achieve cost savings through economies of scale.
There are different types of mergers, such as horizontal mergers (between competitors in the ...
Yes, I have experience testing transformers in various settings.
I have experience testing transformers in industrial settings to ensure proper functioning.
I am familiar with using multimeters and other testing equipment to check for voltage, current, and resistance.
I have tested transformers for efficiency and performance, identifying any issues and making necessary repairs.
I have also conducted routine maintenance che...
An isolator is a device used to disconnect a circuit from the power supply, ensuring the safety of personnel working on the circuit.
An isolator is used to physically disconnect a circuit from the power supply, allowing maintenance work to be carried out safely.
It is often used in conjunction with a lockout/tagout system to prevent accidental re-energization of the circuit.
Isolators are commonly found in electrical pane...

The Bayer process is a method for refining bauxite into alumina, which is the precursor to aluminum production.
The Bayer process involves crushing and grinding bauxite ore, then mixing it with sodium hydroxide at high temperatures to dissolve the alumina content.
The resulting solution is filtered to remove impurities, then cooled and seeded to promote the precipitation of pure alumina hydrate.
The alumina hydrate is the...
The most important dimensionless number is the Reynolds number, as it determines the flow regime of a fluid and is crucial in fluid dynamics.
Reynolds number is used to predict flow patterns in different fluid flow situations
It is defined as the ratio of inertial forces to viscous forces in a fluid flow
Reynolds number helps in determining whether the flow is laminar, turbulent, or transitional
It is widely used in engine...
The equation that correlates HT and fluid flow is the Darcy-Weisbach equation.
The Darcy-Weisbach equation relates the head loss due to friction in a pipe to the velocity and diameter of the pipe, as well as the friction factor.
It is commonly used in fluid mechanics and hydraulic engineering to calculate pressure drop in pipes.
The equation is expressed as: hL = f * (L/D) * (V^2/2g), where hL is the head loss, f is the f...
Systems in thermodynamics refer to the specific region of space or a quantity of matter under study.
A system can be open, closed, or isolated based on the exchange of matter and energy with its surroundings.
Examples of systems include a gas in a container, a piston-cylinder assembly, or a steam turbine.
Thermodynamic properties such as temperature, pressure, and volume are used to describe the state of a system.
The firs...
Dry steam has low moisture content and high temperature, while wet steam has high moisture content and lower temperature.
Dry steam is produced when water is heated to its boiling point and vaporizes without any liquid water droplets present.
Wet steam contains water droplets suspended in the steam, resulting in a lower temperature compared to dry steam.
Dry steam is commonly used in steam turbines for power generation, w...
