Tps Infrastructure Interview Questions, Process, and Tips

A bar bending schedule is a document that provides details of reinforcement steel bars used in a construction project.

• It includes information such as bar mark, bar size, quantity, shape, and bending details.

• It helps in estimating the quantity of steel required and ensures proper placement of reinforcement in the structure.

• Example: Bar Bending Schedule for a beam will list the number of bars, their lengths, and bending

The process of estimating costs involves analyzing project requirements, materials, labor, equipment, and overhead expenses to determine the total cost of a construction project.

• Gather project requirements and specifications

• Identify materials needed for the project

• Estimate labor costs based on the scope of work and labor rates

• Calculate equipment costs for machinery and tools required

• Factor in overhead expenses such as ...read more

Planning a layout involves analyzing the specific drawing, identifying key elements, determining measurements, and ensuring proper placement.

• Carefully study the provided drawing to understand the overall design and dimensions.

• Identify key elements such as walls, doors, windows, and structural components.

• Use measuring tools to determine accurate distances and dimensions for each element.

• Consider factors like traffic flo...read more

IC engines use internal combustion while SI engines use spark ignition.

• IC engines use a fuel-air mixture that is ignited by compression, while SI engines use a spark plug to ignite the mixture

• IC engines are typically used in diesel vehicles, while SI engines are used in gasoline vehicles

• IC engines are more fuel-efficient but produce more emissions than SI engines

• IC engines have a higher compression ratio than SI engine...read more

CNG does not have an octane number as it is a fuel with a different composition.

• CNG stands for Compressed Natural Gas

• Octane number is a measure of a fuel's ability to resist knocking

• CNG is primarily composed of methane

• CNG has a higher octane rating than gasoline

Horsepower is a unit of power used to measure the rate at which work is done.

• Horsepower is commonly used to describe the power output of engines and motors.

• One horsepower is equivalent to 746 watts.

• The term 'horsepower' was coined by James Watt, who compared the power output of steam engines to the work done by horses.

• Horsepower can be calculated using the formula: horsepower = (torque x rpm) / 5252.

Two stroke engines have a power stroke in every revolution while four stroke engines have a power stroke in every other revolution.

• Two stroke engines have a simpler design and are lighter than four stroke engines.

• Four stroke engines are more fuel-efficient and produce less pollution than two stroke engines.

• Two stroke engines are commonly used in small power tools and motorcycles while four stroke engines are used in ca...read more

The octane number of CNG is typically between 120 and 130.

• CNG stands for compressed natural gas

• Octane number is a measure of a fuel's ability to resist knocking

• Higher octane numbers indicate better performance in high-compression engines

Horsepower is a unit of power used to measure the output of engines and motors.

• Horsepower is the amount of work an engine can do over time.

• It was originally defined as the power needed to lift 550 pounds one foot in one second.

• One horsepower is equivalent to 746 watts.

• Horsepower is commonly used to rate the power of cars, boats, and other vehicles.

• Higher horsepower generally means better acceleration and top speed.

4 stroke engines have separate intake, compression, power, and exhaust strokes, while 2 stroke engines combine intake and compression in one stroke and power and exhaust in another.

• 4 stroke engines have a more complex design with separate components for each stroke.

• 2 stroke engines are simpler in design and have fewer moving parts.

• 4 stroke engines are more fuel efficient and produce less pollution.

• 2 stroke engines have...read more

The purpose of a differential is to allow the wheels on an axle to rotate at different speeds while still receiving power from the engine.

• Allows wheels on an axle to rotate at different speeds

• Helps in turning corners smoothly

• Prevents wheel slippage on different terrains

• Balances power distribution between wheels

• Commonly found in vehicles with rear-wheel or all-wheel drive

Material selection depends on the application's requirements and constraints.

• Consider mechanical, thermal, electrical, and chemical properties of materials.

• Evaluate cost, availability, and environmental impact.

• Examples: steel for structural applications, aluminum for lightweight components, plastics for insulation.

• Select materials that meet regulatory requirements and industry standards.

• Perform testing and analysis to
