Some important measurement techniques that you should be familiar with for the practical component of Mechanical Engineering include:

- Calibration: Understanding the process of calibrating various instruments and equipment used in mechanical engineering experiments.
- Dimensional Metrology: Knowledge of measuring instruments such as Vernier calipers, micrometers, dial indicators, and their proper usage.
- Force and Torque Measurement: Understanding the techniques and instruments used to measure forces and torques, such as load cells and torque transducers.
- Pressure Measurement: Familiarity with pressure gauges, manometers, and pressure transducers, and their application in measuring pressure in mechanical systems.


Material testing is an essential part of mechanical engineering. Some common material testing techniques include:

- Tensile Testing: Understanding the procedure for performing tensile tests on materials to determine their mechanical properties such as yield strength, ultimate tensile strength, and elongation.
- Hardness Testing: Familiarity with different hardness testing methods such as Rockwell, Brinell, and Vickers hardness tests, and the ability to interpret the results.
- Impact Testing: Knowledge of conducting Charpy and Izod impact tests to evaluate the toughness and impact resistance of materials.
- Fatigue Testing: Understanding the procedure for performing fatigue tests to determine the endurance limit and fatigue life of materials under cyclic loading.


In addition to measurement and material testing, you should also be familiar with various experimental techniques used in mechanical engineering. These include:

- Fluid Mechanics Experiments: Knowledge of experimental setups and procedures for conducting experiments related to fluid flow, pressure drop, and flow rate measurements.
- Thermodynamics Experiments: Understanding the setup and procedures for experiments involving heat transfer, refrigeration, and energy conversion.
- Machine Component Testing: Familiarity with experimental techniques for testing machine components such as bearings, gears, and shafts to evaluate their performance and durability.
- Control Systems Experiments: Knowledge of experimental setups and procedures for studying the behavior and control of mechanical systems using feedback control techniques.

By being familiar with these laboratory techniques and procedures, you will be well-prepared for the practical component of the Mechanical Engineering optional subject. Remember to practice these techniques under the guidance of a qualified instructor and adhere to all safety protocols while conducting experiments in the laboratory.
