Large Strain And Small Strain.docx

Please watch the video and explain the meaning of LARGE STRAIN and SMALL STRAIN. Another question is, what is YOUNG MODULUS? large strain and small strain Strain is deformation of a beam. Deformation divide by original length to find the strain. The Large strain occur when the beam has large deformation. Then it will call large strain. It has a space between the molecule. When force is applied at the beam, molecule will compress. Because of the beam has space between the molecule, it forms large deformation. The small strain occurs when the beam has small deformation and it will call small strain. It has small space between them the molecule. When apply the force to the beam, the molecule will less compress. Young modulus

The Young's modulus directly Measures the stiffness of the Solid material. It defines the relationship between stress and strain in a material or beam . Young’s modulus (E) is a measure of the ability of a material to withstand changes in length when under length wise tension or compression. Young’s modulus (E) is a measure of the ability of a material to withstand changes in length when under length wise tension or compression. Young's modulus is also used in order to predict the deflection that will occur in a statically determinate beam when a load is applied at a point in between the beam's supports.
