AVTEC Graduate Engineer Interview Questions and Answers

Q1. 1.Difference between 1st angle &3rd angle projection 2.Stress strain graphs for different materials 3. Material properties etc
Ans. 
1st angle and 3rd angle projection differ in the placement of the object and the observer in relation to the projection plane.
• 1st angle projection places the object in front of the projection plane, while 3rd angle projection places the object behind the projection plane.

• In 1st angle projection, the observer views the object from the opposite side of the projection plane, while in 3rd angle projection, the observer vie...read more

Q2. What is young's modulus and ultimate tensile strength? And what are their SI units?
Ans. 
Young's modulus is a measure of stiffness of a material while ultimate tensile strength is the maximum stress a material can withstand.
• Young's modulus is the ratio of stress to strain in a material under tension or compression.

• Ultimate tensile strength is the maximum stress a material can withstand before breaking.

• Young's modulus is measured in pascals (Pa) while ultimate tensile strength is measured in newtons per squ

Q4. What is coefficient of performance input/output
Ans. 
Coefficient of performance (COP) is the ratio of output heat to input work or energy.
• COP is used to measure the efficiency of a heat pump or refrigeration system.

• It is calculated by dividing the output heat by the input work or energy.

• A higher COP indicates a more efficient system.

• For example, a heat pump with a COP of 3 can produce three units of heat for every unit of energy input.

• COP can also be expressed in terms o...read more

Q5. How the otto cycle constants volume this process,
Ans. 
The Otto cycle is a constant volume process used in internal combustion engines.
• The Otto cycle consists of four processes: intake, compression, combustion, and exhaust.

• During the intake process, the fuel-air mixture is drawn into the cylinder.

• During the compression process, the mixture is compressed to a smaller volume, increasing its temperature and pressure.

• During the combustion process, the mixture is ignited, causi...read more

Q6. What is the Duel cycle principles -both constant volume, and pressure
Ans. 
Dual cycle principles involve both constant volume and pressure processes in an engine cycle.
• Dual cycle is a combination of Otto and Diesel cycles.

• It involves two constant volume and one constant pressure processes.

• The first constant volume process is isentropic compression.

• The constant pressure process is combustion.

• The second constant volume process is isentropic expansion.
