10+ Oet Trainer Interview Questions and Answers

Types of fluids include air, water, refrigerants. Coefficient of performance is a measure of efficiency in heat pumps and refrigeration systems.

• Types of fluids: air, water, refrigerants

• Coefficient of performance measures efficiency in heat pumps and refrigeration systems

• Examples: COP of a heat pump is the ratio of heat output to energy input

Welding is a fabrication process that joins materials, usually metals, by melting them together.

• Welding involves using heat to melt and fuse materials together

• Common types of welding include MIG, TIG, and stick welding

• Welding is used in various industries such as construction, automotive, and aerospace

• Examples of welded products include bridges, pipelines, and metal sculptures

Alloy steel is a type of steel that contains other elements besides iron and carbon, while mild steel is a type of carbon steel with low carbon content.

• Alloy steel has higher strength, hardness, and wear resistance compared to mild steel.

• Alloy steel is more expensive than mild steel due to the additional alloying elements.

• Examples of alloy steel include stainless steel, tool steel, and high-strength low-alloy steel.

• Mild steel is easier to weld and form compared to alloy steel...read more

Thermodynamics is the study of energy and its transformations in systems.

• It deals with the relationships between heat, work, and energy.

• It includes the study of laws and principles governing energy transfer and conversion.

• Examples include the analysis of engines, refrigerators, and chemical reactions.

• Thermodynamics is essential in understanding the behavior of gases, liquids, and solids.

• It has applications in various fields like engineering, physics, chemistry, and biology.

Mechanism refers to the process or system by which something operates or functions.

• It explains how something works or how it is done

• It can be a physical or chemical process

• Examples include the mechanism of action of a drug, the mechanism of a machine, or the mechanism of a biological process

• It can also refer to the underlying principles or theories behind a phenomenon

Viscosity is a measure of a fluid's resistance to flow.

• Viscosity is often referred to as thickness or stickiness of a fluid.

• It is caused by friction between molecules in a fluid as they move past each other.

• High viscosity fluids flow slowly, while low viscosity fluids flow quickly.

• Examples of high viscosity fluids include honey and molasses, while water has low viscosity.

Welding is a process of joining two or more pieces of metal together by melting and fusing them.

• Welding involves using heat to melt the base metals and adding a filler material to create a strong joint.

• Common types of welding include arc welding, MIG welding, TIG welding, and spot welding.

• Welding is used in various industries such as construction, automotive, aerospace, and manufacturing.

• Examples of welded products include bridges, buildings, pipelines, and metal furniture.

Tenses in grammar indicate the time of an action or state of being.

• Tenses are used to show when an action takes place - past, present, or future.

• There are three main tenses: past, present, and future.

• Each tense can be further divided into simple, continuous, perfect, and perfect continuous forms.

• Examples: Past tense - I walked to the store. Present tense - She is reading a book. Future tense - They will arrive tomorrow.

The present perfect tense is used to describe actions that happened at an unspecified time in the past or have relevance to the present.

• Formed with 'have' or 'has' + past participle of the verb

• Used to talk about experiences, changes, or actions that started in the past and continue into the present

• Often used with time expressions like 'already', 'yet', 'just', 'recently', etc.

• Examples: 'I have finished my homework.' 'She has lived in Paris for five years.'

Types of welding include MIG, TIG, stick, and flux-cored welding.

• MIG welding uses a wire electrode and shielding gas to create a strong bond.

• TIG welding uses a tungsten electrode and inert gas for precise and clean welds.

• Stick welding uses a consumable electrode coated in flux to create a strong bond.

• Flux-cored welding uses a tubular wire filled with flux for outdoor and windy conditions.

Hook's law states that the force needed to extend or compress a spring by a distance is directly proportional to that distance.

• Force needed to extend or compress a spring is directly proportional to the distance

• Mathematically expressed as F = kx, where F is the force, k is the spring constant, and x is the distance

• The law applies to elastic materials like springs and rubber bands
