The hypothesis used in developing the stress and strain in the shaft is that all points on a cross-section of the shaft experience the same angle of twist. The angle of twist for a section of length L ...

CROSS-SECTIONAL analysis, by means of which is investigated the behaviour of a cross-section of the population at a given point in time, is a convenient method in many fields of research where age ...

A second experiment can be carried out to investigate experimentally how the resistance of a metallic conductor at constant temperature depends on the area of cross section. The above experiment ...
