At a point in a plate subjected to plane stress loading along its surface, the cartesian stress components acting on the y-face of an element oriented along the (x,y) frame are σy=8MPa and τxy=16MPa,

The maximum allowable tensile (normal) stress, to prevent fracture of the material, is σo=40MPa.

What is the maximum permissible value (in MPa) for the normal stress on the x-face, σmaxx, to ensure that the material will not fracture?

σmaxx=
