Homework Help: Midship section problem from naval architect

  1. Sep 16, 2011 #1
    Dear everyone,

    Recently i attend a course and my homework in below. As I have leave school for ten years, lots of knowledge have forgotten, so pls help me resolve it. Sincerely thanks your help.

    The midship section is subjected to a moment of Mxx = 80,000 tm Hogging. The idealized structural members contributing to the longitudinal strength of the hull girder are as shown in the figure below:
    (a) Determine the location of the neutral axis NA
    (b) Determine the sectional modulus of the midship section
    (c) Determine the stress at the deck and bottom plates
    (d) Determine the safety factor for yielding if the material yield stress is 200 MPa
    (e) What are the structural advantages of using angled-section at the top deck?
    (f) Search the internet for the likely hull failure modes. Write up your findings, in not more than 300 words, about the design practice to prevent these failure modes.
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
