Bending Moment - Composite Material

Click For Summary
SUMMARY

The discussion centers on solving a bending moment problem involving composite materials, specifically using the transformation equations to convert a composite bar into a homogeneous one. The participant is tasked with calculating the new section modulus (Z), moment of inertia (I) about the neutral axis, and the resulting stresses, with a specified moment of M=60 N.m. The conversation emphasizes the importance of showing work for assistance and adhering to academic integrity guidelines.

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


Homework Equations


Transformation Equations: Z = z * E / E(ref)


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 textbook. 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.
