The state of stress at a point in a member is shown on the rectangular stress element in (Figure 4) where the magnitudes of the stresses are |σx|=137 MPa and |τxy|=70 MPa. Determine the state of stress on an element rotated 85∘ clockwise from the element shown. Answer should be listed as σx′=, σy′=, τx′y′= in MPa

Transcribed Image Text:### Figure 4: Stress Components on an Element
This diagram illustrates a two-dimensional element subjected to stress. The element is represented as a square.
#### Components of Stress:
- **Normal Stress (\(\sigma_x\)):**
- Shown acting on the right face of the element, directed inward, symbolizing tensile or compressive stress along the x-axis.
- **Shear Stress (\(\tau_{xy}\)):**
- Illustrated on the top and left faces of the element.
- The shear stress on the top face is directed to the left.
- The shear stress on the left face is directed upward.
#### Description:
- The diagram represents the concept of stress in mechanics, showing how both normal and shear stresses can act on an elemental portion of a material. This visualization helps in understanding how forces and moments are distributed in solid mechanics.
