Sparrow Education Interview Questions and Answers

There are various types of technical tools used by mechanical engineers for designing, analyzing, and manufacturing mechanical systems.

• Hand tools (e.g. wrenches, screwdrivers)

• Power tools (e.g. drills, grinders)

• Measurement tools (e.g. calipers, micrometers)

• Modeling and simulation software (e.g. CAD, FEA)

• Testing equipment (e.g. dynamometers, strain gauges)

There are several types of exhaust systems in a vehicle, including single exhaust, dual exhaust, and high-performance exhaust.

• Single exhaust system: consists of one exhaust pipe and one muffler.

• Dual exhaust system: consists of two separate exhaust pipes and mufflers.

• High-performance exhaust system: designed to improve engine performance and efficiency.

• Other types may include side exhaust, cat-back exhaust, and axle-back exhaust.

The symbol for flatness is a straight line and for roughness is a series of peaks and valleys.

• Flatness is represented by a straight line with no curves or bumps.

• Roughness is represented by a series of peaks and valleys that indicate the surface is not smooth.

• The symbol for flatness is often used in engineering drawings to indicate a surface that must be perfectly flat.

• The symbol for roughness is often used in manufacturing to indicate a surface that requires additional proces...read more

• Training employees...read more

The least count of a measuring instrument is the smallest value that can be measured by the instrument.

• Least count is determined by the smallest division on the scale of the instrument.

• It is important to consider the least count when selecting an instrument for a particular measurement.

• Examples of instruments and their least counts include: ruler (0.1 mm), micrometer (0.01 mm), thermometer (0.1°C).

7QC tools are a set of techniques used for quality control and problem-solving in manufacturing and service industries.

• Check sheets: Used to collect and analyze data in a systematic way.

• Histograms: Visual representation of data distribution.

• Pareto charts: Helps identify the most significant factors contributing to a problem.

• Cause-and-effect diagrams: Also known as fishbone diagrams, used to identify root causes of a problem.

• Scatter diagrams: Show the relationship between two ...read more
