Final answer:
To determine the axial displacement and strain of a loaded rod, you need to use the equations for strain and elongation.
Step-by-step explanation:
To determine the axial displacement and strain of the rod loaded axially, we can use the equation for strain and the equation for elongation:
Strain: Strain is defined as the change in length divided by the original length. In this case, the axial displacement is the change in length. So, strain = axial displacement / original length.
Elongation: Elongation is the change in length due to stress. In this case, the stress is the load per unit length. So, elongation = stress / (Young's modulus * cross-sectional area).
By substituting the given values into these equations, we can calculate the axial displacement and strain at different locations along the rod.
