Homework Help: Transverse loading

  1. Jan 5, 2010 #1
    for the beam in the diagram
    Capture.JPG

    E=2.1e6kg/cm2
    Ixx=3600cm4

    find:
    the principle stresses in the beam

    the strains ex, ez e(45) found on the strain rosette placed at point 4



    i have only managed to find the principle stress z which i found at point 1 --- 1406kg/cm2 where would i find the other stresss? how can i find the stress on the x axis? to find z i used -Y*M/I knowing that the maximum moment is at the wall and is -5.0625[t*m]

    to find the strains i just divide by E and i get the z strain=6.67e-4 how can i find the x strain? once i find the x strain can i say the shear strain is 0?
