An element in plane stress on the fuselage of an airplane (figure part a) is subjected to compressive stresses with a magnitude of 42 MPa in the horizontal direction and tensile stresses with a magnitude of 9.5 MPa in the vertical direction (see figure part b). Also, shear stresses with a magnitude of 15.5 MPa act in the directions shown.
having a brittle material, it has properties of Sut-205 Mpa and Sy= 620 Mpa. Use modified Mohr's theory to determine the factor of safety in the following states of plane stress
(a) 9.5 MPa ? (b) 42 MPa 15.5 MPa
