AIM: To verify that the fundamental frequency of vibration of a steel bar clamped at one end is inversely proportional to the square of its and to measure the Young’s modulus of the bar. Young’s modulus, numerical constant, named for the 18th-century English physician and physicist Thomas Young, that describes the elastic properties of a solid undergoing tension or compression in only one direction, as in the case of a metal rod that after being stretched or compressed lengthwise returns to its original length. The wire stretches and gravitational energy is lost. In order to determine the Tensile Strength of the brass material being measured, we must find what maximum mass the brass wire can bear before fracture. The magnitude of its anglar momentum about the point of projection is, If the diameter of the wire is doubled and its length is halved then its Young's modulus (Y). and Differentiability.
