Q7. Types of engines functioning of different types of comparisons

Ans.

Different types of engines have varying functions and comparisons, such as internal combustion engines vs electric motors.

  • Internal combustion engines use fuel combustion to generate power, while electric motors use electricity.

  • Diesel engines are more fuel efficient than gasoline engines.

  • Turbocharged engines provide more power by compressing air before it enters the combustion chamber.

  • Hybrid engines combine internal combustion engines with electric motors for improved efficien...read more

Q8. What is stress and type stresses

Ans.

Stress is a force that causes deformation in a material. Types include tensile, compressive, shear, and torsional stresses.

  • Stress is a force applied to a material that causes it to deform.

  • Tensile stress occurs when a material is being pulled apart.

  • Compressive stress occurs when a material is being pushed together.

  • Shear stress occurs when a material is being pushed in opposite directions.

  • Torsional stress occurs when a material is being twisted.

Q9. Aerodynamic forces on wing and types drags

Ans.

Aerodynamic forces on wing include lift and drag. Types of drag include parasite drag, induced drag, and wave drag.

  • Aerodynamic forces on a wing include lift (upward force) and drag (backward force)

  • Types of drag include parasite drag (caused by form and skin friction), induced drag (caused by lift), and wave drag (caused by supersonic flight)

  • Parasite drag can be reduced by streamlining the aircraft's shape

  • Induced drag can be reduced by increasing aspect ratio or using winglets...read more

Q12. What is flatness

Ans.

Flatness refers to the condition of a surface having no deviations or variations from a perfectly flat plane.

  • Flatness is a measure of how closely a surface approaches a perfect plane.

  • It is often specified in engineering drawings to ensure proper fit and function of parts.

  • Flatness can be measured using tools such as straight edges, surface plates, or coordinate measuring machines.

  • Examples of flatness requirements include the surface of a table, a mirror, or a machined part.

Add your answer

Q13. What is parallelism

Ans.

Parallelism is the concept of performing multiple tasks simultaneously or in parallel.

  • Parallelism can be achieved through multi-threading, multi-processing, or distributed computing.

  • It helps in improving performance and efficiency by utilizing available resources effectively.

  • Examples include running multiple applications at the same time on a computer, or executing multiple instructions simultaneously in a processor.
