Measurement and Calibration in Mechanical Engineering Quiz

Thermocouples are frequently employed for temperature measurement due to their ability to generate a voltage proportional to temperature.

Calibration involves aligning an instrument to a known standard to ensure accurate and reliable measurements.

Durometers are instruments specifically designed for measuring the hardness of materials.

Zero error in measurement occurs when an instrument reads a value other than zero in the absence of the measured quantity.

Micrometer screw gauges are employed to measure small linear distances with exceptional precision in mechanical engineering applications.

Pressure is measured in Pascals (Pa), the SI unit, representing one newton per square meter.

Tolerance in mechanical engineering defines the permissible variation from a specified dimension, indicating precision requirements.

Strain gauges operate on the principle that the electrical resistance changes proportionally to the applied strain.

NIST, or the National Institute of Standards and Technology, sets and maintains standards for various measurements in the United States.

ISO, or the International Standards Organization, establishes international standards, including those related to calibration in various fields.

Dial indicators are used to measure small linear distances with high precision in mechanical engineering applications.

Profilometers are instruments used to measure the surface roughness of components in mechanical engineering.

Dynamometers are used to measure torque and power in mechanical engineering applications.

Profilometers are instruments designed for measuring the surface roughness of components in mechanical engineering.

Vernier scales are utilized to measure small linear distances with increased precision in mechanical engineering applications.
