A brittle material has the properties S_ut = 30 kpsi and S_uc = 90 kpsi. Using the brittle CoulombMohr and modified-Mohr theories, determine the factor of safety for the following states of plane stress.

(a) σ_x = 25 kpsi, σ_y = 15 kpsi

(b) σ_x = 15 kpsi, σ_y = -15 kpsi

(d) σ_x = -15 kpsi , σ_y = 10 kpsi , τ_xy = -15 kpsi

(e) σ_x = -20 kpsi , σ_y = -20 kpsi , τ_xy = -15 kpsi
