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 ...

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 ...

"The probability (per unit area) of a nucleus capturing a neutron at a given kinetic energy is called neutron-capture cross section," Thanos Stamatopoulos, first author of the paper, told Phys.org.
