Concept explainers

Metrology of surface finish

In general terms, the application of scientific principles in the study of measurements is known as metrology. When speaking about measurement, it could be of time, length, microstructures, grain structures, internal crystal discontinuities, surface roughness, measurements of angles, height, width, and so on. While coming to the domain of mechanical engineering, metrology is considered the science of measurements of surface finish, length, surface texture, and angles.

Question

2. A long cylindrical log of specific gravity 2/3 will float in water with its axis
horizontal. As its length gradually is reduced it will float in the same position.
If its length is reduced so that it is only a fraction of its diameter, it will float
with its axis vertical. What is its diameter-to-length ratio for which it will just
float with its axis vertical?
