Basic measurement techniques
Principle
Caliper gauges, micrometers and spherometers are used for the accurate measurement of lengths, thicknesses, diameters and curvatures. Measuring procedures, accuracy of measurement and reading accuracy are demonstrated.
- Foundation of every practical sciences lab course
- Aquire the skills to measure basic mechanical variables
- Realise the limits of measuring accuracy
- Combine different measurements to determine a quantity of interest
- Determine curvatures using the spherometer
