A Rectangular Plate in Plane Stress Is Subjected to Normal $\sigma_{x}=35 \mathrm{MPa}, \sigma_{y}=26 \mathrm{MPa}$

question 54

Short Answer

A rectangular plate in plane stress is subjected to normal stresses $\sigma_{x}=35 \mathrm{MPa}, \sigma_{y}=26 \mathrm{MPa}$ , and shear stress $\tau_{x y}=14 \mathrm{MPa}$ . The ratio of the magnitudes of the principal stresses $\left(\sigma_{1} / \sigma_{2}\right)$ is approximately: (A) $0.8$
(B) $1.5$
(C) $2.1$
(D) $2.9$
