Manufacturing and Quality Engineer Interview Questions and Answers

The least count of a vernier caliper is the smallest measurement that can be read on the scale.

• The least count is determined by the number of divisions on the main scale and the vernier scale.

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

• For example, if the main scale has divisions of 1 mm and the vernier scale has 10 divisions that match with 9 divisions on the main scale, the least count would be 0.1...read more

SI units are the standard units used to measure physical quantities in the International System of Units.

• SI units are used to measure physical quantities such as length (meter), mass (kilogram), time (second), electric current (ampere), temperature (kelvin), amount of substance (mole), and luminous intensity (candela).

• For example, the SI unit for length is meter, for mass is kilogram, for time is second, for electric current is ampere, for temperature is kelvin, for amount of...read more

The least count of a micrometer is the smallest measurement that can be read on the scale of the micrometer.

• The least count of a micrometer is typically 0.01 mm or 0.001 mm, depending on the type of micrometer.

• It is determined by the number of divisions on the thimble and the main scale of the micrometer.

• For example, a micrometer with 50 divisions on the thimble and a main scale reading in mm would have a least count of 0.01 mm.

Strength of materials refers to the ability of a material to withstand applied forces without failure.

• Strength of materials is a fundamental concept in engineering that involves analyzing the behavior of materials under different types of loads.

• It is important for engineers to understand the strength properties of materials in order to design structures and components that can safely support the intended loads.

• Factors that affect the strength of materials include material com...read more
