Question

Determine the principal planes and the principal stresses for the state of plane stress resulting from the superposition of the two states of stress shown. Given: X = 60 MPa and Y = 20 MPa.

Determine the orientation of the principal plane in the first and second quadrant.

Determine the maximum/minimum principal stresses

The image illustrates two diagrams related to stress analysis in a material. 1. **Left Diagram**: - A square is shown with its sides aligned to the horizontal and vertical axes. - Two double-headed arrows are displayed: - The horizontal arrow is labeled "X," indicating the horizontal direction of force or stress. - The vertical arrow is labeled "Y," indicating the vertical direction of force or stress. - The arrows suggest a coordinate system for analyzing stress, with no specific magnitude indicated. 2. **Right Diagram**: - Another square is shown, rotated at an angle. - The square features an internal point from which the forces emanate. - The square is tilted such that one diagonal arrow points outward at an angle labeled "30°" from the horizontal. - This diagonal arrow is labeled "80 MPa" (megapascals), representing the magnitude and direction of the applied stress. The "+" symbol between the diagrams implies a superposition or combination of effects from the two states of stress. This could be relevant for calculations or analyses involving principal stresses or transformations.
