Chandigarh College of Engineering and Technology Lecturer Interview Questions and Answers

Criteria are essential for effective teaching and learning in the classroom.

• Criteria help to set clear expectations for students

• Criteria provide a basis for assessment and feedback

• Criteria can be used to differentiate instruction for diverse learners

• Examples of criteria include rubrics, checklists, and scoring guides

A 4 stroke engine has four processes: intake, compression, combustion, and exhaust.

• Intake: Fuel and air enter the cylinder

• Compression: The piston compresses the fuel and air mixture

• Combustion: The spark plug ignites the mixture, causing an explosion that pushes the piston down

• Exhaust: The piston pushes the exhaust gases out of the cylinder

Factor of safety is the ratio of the maximum stress a material can withstand to the actual stress it is subjected to.

• It is a measure of how much stronger a material is than the maximum stress it will encounter.

• It is calculated by dividing the maximum stress a material can withstand by the actual stress it is subjected to.

• A factor of safety greater than 1 indicates that the material is stronger than the maximum stress i...read more

Factor of safety differs in civil and mechanical engineering contexts

• In civil engineering, factor of safety is used to ensure the safety of structures and materials under loads and stresses

• In mechanical engineering, factor of safety is used to ensure the safety of mechanical components and systems under loads and stresses

• Civil engineering typically uses a higher factor of safety than mechanical engineering

• For example, ...read more

Stress strain curve for mild steel shows the relationship between stress and strain during deformation.

• Initially, stress and strain are proportional to each other in the elastic region.

• Beyond the elastic limit, plastic deformation occurs and stress increases while strain also increases.

• The point of maximum stress is the ultimate tensile strength.

• The point of fracture is the breaking stress.

• The area under the curve repr...read more
