Final answer:
To analyze stress and strain on a square aluminum plate, we calculate stress using the formula σ = F/A, and strain as ε = σ/Y. Young's modulus for aluminum is needed to calculate the elongation of the plate under stress, with the formula ΔL = ε × L.
Step-by-step explanation:
A square aluminum plate with sides of 2.0 m subjected to a force will experience stress and strain based on its material properties. To analyze these, we must know the Applied Force (F), the Cross-Sectional Area (A), and the material's Young's Modulus (Y).
The stress (σ) is calculated using the formula: σ = F/A, and strain (ε) can be evaluated as: ε = σ/Y, where Young's modulus for aluminum is known (approximately 70 GPa).
To find the elongation (ΔL) of the plate under stress, we can use the formula: ΔL = ε × L, where L is the initial length of the plate. For the complete analysis, factual data regarding the force and plate thickness would be required.
