    Page 3 - Question 2
    Except that let M=60 N.m (instead of 75)

    2. Relevant equations
    Transformation Equations: Z = z * E / E(ref)

    3. The attempt at a solution
    Transforming the composite bar to a homogeneous one using the transformation equations, then computing the stresses.

    Hi, CivilWork. You must show your work to get help. Read the PF rules. Also read your text book. We aren't allowed to tell you how to approach or solve a problem. To do so would be cheating on your assignment. You must first show a valid attempt, and then someone might check your math.
