You're on a roll — Let's break down this problem step by step, using the information provided and making reasonable assumptions based on typical physics problems involving rods. We will assume the rod mentioned here is the same one from the previous problem, with a diameter of 80 mm. a) Strain Strain () is defined as the change in length ( L) divided by the original length (L_0). From your written work, it appears you are using L = (20 - 28) and L_0 = 80. Step 1: Calculate the change in length ( L). L = 20 mm - 28
