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-section animation of the early stages of a 3D simulation of a grazing, fast giant impact using 30 to 100 million particles, coloured by its material or its internal energy, related to its ...

Cross sections tell physicists how likely particles are to interact in a given way. Imagine two billiard balls rolling toward one another. The likelihood of a collision depends on easy-to-grasp ...
