Youngs modulus of elasticity is ratio between stress and strain. It can be expressed as: Example. Find the youngs modulus of elasticity for the material which is 200 cm long, 7. 5 cm wide and 15 cm deep. Tie material is subjected to axial force of 4200 KN. As a result material is stretched 2. 67 cm.Modulus of Elasticity is a measure of stiffness of an elastic material. It is used to describe the elastic properties of objects like wires, rods or columns when they are stretched or compressed. It can be used to predict the elongation or compression of an object as modulus of elasticity worked example
Youngs Modulus Calculations Relate to Elasticity The calculations from Youngs modulus depends on the applied force, the type of material and the area of the material. The stress of the medium relates to the ratio of the applied force with respect to the crosssectional area.
An elastic modulus, or modulus of elasticity, is the mathematical description of an object or substance's tendency to be deformed elastically (i. e. nonpermanently) when a force is applied to it. The elastic modulus of an object is defined as the slope of its stressstrain curve in the elastic deformation region. Modulus of elasticity units. The units of the Young's modulus are the same as the units of pressure and stress: Pascals or newtons per square meter. In SI units, 1 Pa 1 N 1 m2 1 kg m s2 m2 1 kg (m s2) If you are interested in mechanics, try the torque calculator as well.modulus of elasticity worked example Young's Modulus Modulus of Elasticity (or Tensile Modulus) Hooke's Law. Modulus of Elasticity, or Young's Modulus, is commonly used for metals and metal alloys and expressed in terms 106 lbfin2, Nm2 or Pa. Tensile modulus is often used for plastics and is expressed in terms 105 lbfin2 or GPa.
Youngs modulus is the ratio of normal stress to normal strain within the range of elastic limits. It can also be tensile stress to tensile strain or compressive stress to compressive strain. Stress, strain& youngs modulus of elastictcity calculation can be easily explain through example. modulus of elasticity worked example Chapter 13 ELASTIC PROPERTIES OF MATERIALS elastic body Young's modulus stress bulk modulus strain modulus of rigidity elastic limit Hooke's Law State Hooke's law. Stress and Strain Calculate the strain and stress for various types of deformation. you think of some biological examples of elastic bodies? In this chapter we will examine Young's modulus is the modulus of tensile elasticity. Tensile elasticity indicates the ability of a body to undergo linear deformation. A body undergoes linear deformation when it is stretched or compressed along a longitudinal axis. Young's modulus is given by MODULUS OF ELASTICITY. The modulus of elasticity ( Youngs modulus) E is a material property, that describes its stiffness and is therefore one of the most important properties of solid materials. Mechanical deformation puts energy into a material. The energy is Young's modulus is a mechanical property that measures the stiffness of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear elasticity regime of a uniaxial deformation. Young's modulus is named after the 19thcentury British scientist Thomas Young.
