A region on the surface of a body including a Point P is subjected to a pressure of 200 psi. At Point P the surface normal is given by 27+10+11k Calculations show that the stress state at Point P is given by 20000 3000 -6400 Op = 3000 - 3000 2000 psi -6400 2000 -854.546, Could this calculated stress state be correct?... Does this stress state satisfy the given pressure boundary condition? To receive credit, support you answer with calculations.
