---## Plane Stress AnalysisThe state of plane stress at a point can be described by a known tensile stress σx = 80 MPa, an unknown tensile stress σy, and an unknown shear stress τxy, as indicated in the figure. At this point, the maximum shear stress τmax = 80 MPa, and one of the two principal stresses is ±25 MPa. Determine the two unknown stresses (MPa) σy and τxy respectively.### Description of the Figure:A diagram is presented showing a square element subjected to stresses. The element is oriented with its sides parallel to the x and y axes. The following stresses are applied:- Tensile stress σx acts horizontally to the right along the positive x-axis.- Tensile stress σy acts vertically upwards along the positive y-axis.- Shear stress τxy acts in the plane of the element, with both positive and negative directions indicated.### Answer Choices:- a. 100, 78- b. None- c. 178, 130- d. 130, 76- e. 129, 73### Analysis:To solve for the unknown stresses σy and τxy, you can use the derived principal stress conditions and shear stress equations for plane stress conditions:- Maximum shear stress condition equation- Principal stress condition equation### Note:The solution involves solving a system of equations based on the provided conditions and utilizing appropriate mechanical stress transformation equations.---
