Percentage Elongation Example
Percentage elongation is the increase in gauge length compared to the original length. Percentage Elongation Formula Percentage elongation can be expressed as; Symbolically it can be expressed as; Percentage Elongation Example Find percentage elongation of …
Continue readingYoung’s Modulus of Elasticity Formula & Example
Young’s modulus of elasticity is ratio between stress and strain. It can be expressed as: \[E=\frac{f}{e}\] Example Find the young’s modulus of elasticity for the material which is 200 cm long, 7.5 cm wide and …
