Jaya Hind Industries Junior Engineer Interview Questions and Answers

Gauges are instruments used to measure and display various parameters. There are different types of gauges for different applications.

• Analog gauges - display readings using a needle on a dial, such as a speedometer

• Digital gauges - display readings using numerical digits, such as a digital thermometer

• Pressure gauges - measure pressure of fluids or gases, such as a tire pressure gauge

• Temperature gauges - measure temperat...read more

Least count of vernier caliper is the smallest measurement that can be read accurately.

• It is the difference between the smallest division on the main scale and the smallest division on the vernier scale.

• For example, if the main scale has a smallest division of 0.1 cm and the vernier scale has a smallest division of 0.01 cm, then the least count is 0.01 cm - 0.1 cm = 0.09 cm.

• The least count varies depending on the preci...read more

Undersize and oversize refer to measurements that are smaller or larger than the standard size.

• Undersize refers to a measurement that is smaller than the standard size.

• Oversize refers to a measurement that is larger than the standard size.

• Undersize and oversize can apply to various objects, such as clothing, machinery parts, and tools.

• For example, an undersized bolt may not fit properly in a hole, while an oversized bo...read more

Hardness can be measured using various methods depending on the material. Common methods include Brinell, Rockwell, and Vickers.

• Determine the appropriate method for the material being tested

• Prepare the surface of the material to be tested

• Apply a known force to the material using a specific indenter

• Measure the size of the indentation left on the material

• Calculate the hardness value using the appropriate formula

A defect occurs when there is a deviation from the expected behavior or functionality of a product or system.

• Defects can occur at any stage of the development process, from design to implementation to testing.

• Defects can be caused by human error, faulty equipment, or environmental factors.

• Defects can manifest in various ways, such as crashes, errors, or incorrect output.

• Defects can be detected through various testing m...read more

To reduce defects, identify the root cause and implement corrective actions.

• Conduct thorough analysis of the production process

• Identify the root cause of defects

• Implement corrective actions to address the root cause

• Train employees on proper procedures and quality control

• Regularly monitor and evaluate the effectiveness of the corrective actions

Vernier calipers come in two types: standard and digital.

• Standard vernier calipers have a main scale and a sliding vernier scale.

• Digital vernier calipers have a digital display for easy reading.

• Both types can measure internal and external dimensions, as well as depth and step measurements.
