If young modulus = stress/strain
Wouldn't a different original length affect the value of young modulus ?

With a different original length, there will also be a different change in length, so the ratio of the change in length to the original length stays the same.Ysondh said:If young modulus = stress/strain

According to the definition of young modulus, it is a measure of a material's stiffness or resistance to deformation under stress. This means that the young modulus is only affected by the material's intrinsic properties, such as its molecular structure and bonding, and not by its length.
The relationship between young modulus and length can be better understood by considering Hooke's law, which states that the amount of deformation in a material is directly proportional to the applied stress. This means that the young modulus remains constant regardless of the length of the material, as long as the stress applied is within its elastic limit.
No, the young modulus is a material property that remains constant regardless of any changes in the material's length. Altering the length of a material may change its stiffness or flexibility, but it does not affect its young modulus.
The young modulus of a material is primarily affected by its composition and structure. Other factors that may influence the young modulus include temperature, strain rate, and the presence of defects or imperfections in the material's structure.
Young modulus is a crucial factor in engineering and design, as it helps predict the behavior and performance of materials under different conditions. It is used to determine the maximum stress that a material can withstand before it permanently deforms, and to compare the stiffness of different materials for specific applications.
