. Figure shows the strain-stress curve for a givenmaterial. What are (i) Young's modulus and (ii)approximate yield strength for this material

A material has a length of 5 meters, a cross-sectional area of 0.003 m², and a Young's modulus of 4 x 10^10 N/m². If it experiences a stress of 2 x 10^7 N/m², what is the strain?

To determine Young's modulus of elasticity of the material of a given wire.

The slope of the stress-strain curve in the elastic deformation region is ____________*1 pointa) Elastic modulusc) Poisson’s ratiob) Plastic modulus

A wire of length 4 meters is stretched by a force of 800 N, resulting in a strain of 0.02. What is the Young's modulus of the material?

Write a C program that calculates the stress and strain on an engineering material based onuser input. The program should:Prompt the user to enter the type of material from a list (e.g., "Steel", "Aluminum", "Copper").Depending on the material selected, use predefined values for Young's modulus (E) for eachmaterial (e.g., Steel = 200 GPa, Aluminum = 69 GPa, Copper = 110 GPa).Ask the user to input the force applied (in Newtons) and the cross-sectional area of the material(in square meters).Calculate the stress using the formula: Stress (σ) = Force (F) / Area (A).Ask the user to input the original length of the material (in meters) and the amount it elongated(in meters).Calculate the strain using the formula: Strain (ε) = Elongation (ΔL) / Original Length (L0).Finally, calculate and display the stress and strain on the material.Additional Notes:Make sure to use floating-point variables for accuracy.Provide clear instructions and outputs so the user can easily follow along.Include error checking for invalid inputs (e.g., negative values)
