I have a mechanical engineering assessment and one question I'm stuck on is,
"11. Sketch the cross section of the gantry girder and indicate on it the position of the maximum bending stress. State if this stress is tensile or compressive for this particular example, explain how you decided."
The maximum bending stress (sigma max) I have determined is 18.789MN/m^2 and therefore 'hogging'. Where would I sketch this on the cross section? Is it at the very bottom of the beam as that would be tensile or at the top which would be compressive or is it much more difficult than that? This material has not been covered in class!
