WebFeb 13, 2024 · We calculate the strain is the rod according to the formula: ε = ΔL/L₁ = 3/2000 = 0.0015. We calculate the stress, using the stress formula: σ = F/A = 30×10³ / (1×10⁻⁴) = 300×10⁶ = 300 MPa. Finally, we divide the stress by strain to find the Young's modulus of steel: E = σ/ε = 300×10⁶ / 0.0015 = 200×10⁹ = 200 GPa.

WebStrain Energy Formula. Strain energy is defined as the energy stored in a body due to deformation. The strain energy per unit volume is known as strain energy density and the area under the stress-strain curve towards the point of deformation. When the applied force is released, the whole system returns to its original shape. It is usually ... WebMathematically, it can be expressed as, Stress (σ) = Resisting force (F) Resisting area (A) Resisting force (F) Resisting area (A) Stress is the tensor quantity and it is generally denoted by the symbol ‘σ (Sigma)’. The stress can be classified as follows:-
WebMar 21, 2024 · The answer is strain. Suppose the length of a structure with length L undergoes deformation under stress and its length changes to L’, then its change in length ΔL = L’ – L, and the strain ε is the ratio of the change in length ΔL to the original length L, the formula is as follows: So, what is the unit of strain?
