Stiffness of Shaft in Longitudinal and Transverse Vibrations Formulas

Stiffness of Shaft means that the lateral deflection of the shaft and/or angle of twist of the shaft should be within some prescribed limit. And is denoted by S_s. Stiffness of Shaft is usually measured using the Newton per Meter for Surface Tension. Note that the value of Stiffness of Shaft is always positive.
