You must perform mechanical tests with a linear elastic material (the material follows Hooke's law) applying forces (tension) in the range 0 to Fmax/2 for Sample A and between 0 to Fmax for Sample B. The samples are made of same material but have different geometries (see illustration). (a) Which of the two samples receives the maximum stress (σmax)? (b) Which of the two samples will have the larger length change (ΔLmax)? (c) Plot the expected curves for the two samples in the force-length and stress-strain planes. (d) Clearly indicate the values that the variables force, length, stress, and strain take at the beginning and end of each curve.

Express the relationship between stress and strain in case of non linear elastic material,i.e rubber and polymers. Describe how stress relates with strain in non linear Elastic material.
The femur, the long bone in the thigh, can be modeled as a tube of compact bone for most of its length. The cross-section area of the compact bone in the femur of a 70 kg person is 4.8 x 10-4 m2, a typical value.a. If this person supports his entire weight on one leg, what fraction of the tensile strength of the bone does this stress represent?b. By what fraction of its length does the femur shorten?
A copper wire has a radius of 3.5 mm. When forces of a certain equal magnitude but opposite directions are applied to the ends of the wire, the wire stretches by 5.0×10^-3 of its original length. Young's modulus for copper is 11×10^10 Pa What is the magnitude of the force on either end?
