Bending Moment - Composite Material

  1. Apr 28, 2009 #1
    1. The problem statement, all variables and given/known data
    http://www.apeg.bc.ca/reg/past-exams/documents/May2005-98-BS-6.PDF [Broken]
    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.
    Im getting wrong answers, what are the new z , I about neutral axis, and 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.
