Young Modulus Formula Physics ~ Young s modulus also referred to as the elastic modulus or tensile modulus is a measure of mechanical properties of linear elastic solids like rods wires and such. The first experiments that used the concept of young s modulus in its current form were performed by the italian scientist giordano riccati in 1782 pre dating young s work by 25 years. It is assumed that the proportionality limit of the wire is not exceeded. This means it is a number which represents how easy it is to deform stretch a material. It is the ratio of tensile stress to tensile strain. The bulk modulus k is like young s modulus except in three dimensions. Young s modulus describes tensile elasticity along a line when opposing forces are applied. There are some other numbers exists which provide us a measure of elastic properties of a material. Y σ ε we have y f a l l f l a l as strain is a dimensionless quantity the unit of young s modulus is the same as that of stress that is n m or pascal pa. Although young s modulus is named after the 19th century british scientist thomas young the concept was developed in 1727 by leonhard euler. Indeed recently has been sought by consumers around us, maybe one of you. People now are accustomed to using the internet in gadgets to view video and image information for inspiration, and according to the title of this article I will talk about about Young Modulus Formula Physics. There are other numbers that give us a measure of elastic properties of a material like bulk modulus and shear modulus but the value of young s modulus is most commonly used. Young s modulus formula young s modulus is used to represents how easy it is to deform a material. The first experiments that used the concept of young s modulus in its current form were performed by the italian scientist giordano riccati in 1782 pre dating young s work by 25 years. It is a measure of volumetric elasticity calculated as volumetric stress divided by volumetric strain. The string is pulled by a force of 200 n. Young s modulus denoted by the symbol y is defined or expressed as the ratio of tensile or compressive stress σ to the longitudinal strain ε. Although young s modulus is named after the 19th century british scientist thomas young the concept was developed in 1727 by leonhard euler. Some of these are bulk modulus and shear modulus etc. Young s modulus of the string 5 x 109 n m2. It is the ratio of tensile stress to tensile strain.
Y σ ε we have y f a l l f l a l as strain is a dimensionless quantity the unit of young s modulus is the same as that of stress that is n m or pascal pa. Young s modulus describes tensile elasticity along a line when opposing forces are applied. The young s modulus of the material of the wire is 210 x 10 9 n.
There are some other numbers exists which provide us a measure of elastic properties of a material.
It is the modulus of elasticity. Determine the change in length of the string. It is assumed that the proportionality limit of the wire is not exceeded. Young s modulus describes tensile elasticity along a line when opposing forces are applied.
