Singhal Enterprises Site Engineer Interview Questions and Answers for Freshers

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, po

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 t...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).

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...read more

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.

• Th...read more

Electrical engineering involves the study and application of electricity, electronics, and electromagnetism.

• To install a new transformer, first determine the appropriate location and ensure that the site meets all necessary safety requirements.

• Next, connect the transformer to the power source and ensure that all wiring is properly grounded.

• Finally, test the transformer to ensure that it is functioning correctly.

Stay set installation involves several steps including site preparation, anchor installation, and tensioning.

• Prepare the site by clearing the area and ensuring proper drainage

• Install anchors at the appropriate locations and depths

• Attach the stay set to the anchors and tension it to the required specifications

• Inspect the installation regularly to ensure proper tension and stability

• Make any necessary adjustments or repai

2 ton AC refers to the cooling capacity of an air conditioning unit.

• A 2 ton AC can cool a space of approximately 120-150 square meters.

• The term 'ton' refers to the amount of heat required to melt one ton of ice in 24 hours.

• A 2 ton AC unit typically requires a 220-240 volt electrical outlet.

• The higher the tonnage, the more powerful the AC unit and the larger the space it can cool.

• Other factors such as insulation, ceilin...read more

Hydraulic system is a technology that uses fluids to generate, control, and transmit power.

• Hydraulic systems use a liquid, usually oil, to transmit power.

• They work on the principle of Pascal's law, which states that pressure applied to a fluid in a closed system is transmitted equally to all parts of the system.

• Hydraulic systems are used in a variety of applications, including heavy machinery, aircraft, and automobiles...read more
