Gannon Dunkerley & Co. Interview Questions and Answers

Otto cycle is used in gasoline engines and Diesel cycle is used in diesel engines.

• Otto cycle is a constant volume cycle used in gasoline engines.

• Diesel cycle is a constant pressure cycle used in diesel engines.

• Otto cycle has a higher compression ratio compared to Diesel cycle.

• Otto cycle has a spark plug for ignition while Diesel cycle uses compression ignition.

• Both cycles involve four processes: intake, compression, power, and exhaust.

There are several types of steel, each with different properties and uses. The percentage of steel in a particular alloy can vary.

• Types of steel include carbon steel, alloy steel, stainless steel, tool steel, and high-speed steel.

• The percentage of steel in an alloy can range from as low as 0.2% to as high as 2.1% depending on the type of steel and its intended use.

• For example, carbon steel typically contains around 0.2% to 2.1% carbon, while stainless steel contains at least ...read more

There are two main types of Ramming mass: acidic and basic.

• Acidic Ramming Mass: used for lining induction furnaces and arc furnaces.

• Basic Ramming Mass: used for lining steel ladles and EAF (Electric Arc Furnace).

First law states energy cannot be created or destroyed, second law states entropy always increases, third law states entropy approaches zero at absolute zero.

• First Law: Energy cannot be created or destroyed, only transferred or converted. Example: A car engine converts fuel into mechanical energy.

• Second Law: Entropy of an isolated system always increases over time. Example: Heat always flows from hot to cold objects.

• Third Law: Entropy of a perfect crystal approaches zero as t...read more

As a mechanical engineer, my role involves designing, analyzing, and maintaining mechanical systems and equipment.

• A pump is a mechanical device used to move fluids from one place to another.

• A casting machine is used to create metal parts by pouring molten metal into a mold.

• A compressor is a machine that increases the pressure of a gas by reducing its volume.

• As a mechanical engineer, I would be responsible for selecting, designing, and maintaining these types of equipment.

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, while strain is the measure of the deformation or change in shape.

• Stress is typically measured in units of force per unit area (such as N/m^2 or Pa), while strain is a dimensionless quantity.

• Stress can cause a material to deform or break, while strain is the amount of deformation that occurs.

• Example: A rubber ban...read more

Specific material can be defined as a unique substance or product that possesses distinct characteristics or properties.

• Specific material refers to a particular type of substance or product.

• It is characterized by its unique properties, composition, or functionality.

• Examples of specific materials include stainless steel, aluminum, plastic, wood, etc.

The aspects of verbal communication I find most important are clarity, active listening, and empathy.

• Clarity in communication ensures that the message is easily understood by the recipient.

• Active listening involves fully concentrating on what is being said rather than just passively hearing the words.

• Empathy helps in understanding the emotions and perspectives of the speaker, leading to better communication and rapport.
