Problem 1if the a-36 steel pipe has an outer diameter of 30 mm and inner diameter of 20 mm, determine the factor of safety against yielding of the material at point a according to the a) maximum-shear-stress theory b) maximum-distortion-energy theoryc) if instead this pipe were made from a brittle, high carbon steel, then determine the factor of safety against yielding for the material at point a using the brittle mohr coulombe (bcm) theory (carbon addition can increase the brittleness of steel). in this case, use tensile strength, σyt= 896 mpa and compressive strength, σyc = 2160 mpa (from matweb).note: we suggest re-working this problem for practice, but you can start this problem with stresses that you determined for the two square stress elements solved for in hw 6.
