Homework Help: Calculate stresses with gravitational load and weights instead of forces

  1. Mar 5, 2010 #1
    please see attached for full problem, i will just write what i have attempted here

    stress=youngs modulus x strain; stress = force/area;

    3. The attempt at a solution
    i started off by using F = m x a, where a is gravity, then worked out sum of forces and bending moments.
    this gave me high values for forces at each column. i then divided the forces by the Area, which increased to stresses.

    and question b) i have been doing research on it but still searching

    thanks in advance
