Determine the equivalent state of stress on an element at the same point oriented 60° clockwise with respect to the element shown in the figure below. Suppose that 0₂ = 153 MPa, o₂ = 109 MPa (Figure 1) Figure σy < 1 of 1 75 MPa Ox

A body is subjected to multiple applied loads. The resultant stress at point location (0, 1, 4) meters can be described as or = -5 MPa. Which of the following describes t stress state at this point? Biaxial tension Uniaxial compression Pure shear Uníaxial tension

A rectangular plate (θ =25°) is formed by welding two triangular plates shown in figure. The plate is subjected to a compressive stress of 2.5 MPa in the x-direction and a tensile stress of 15 MPa in the y-direction. Determine the normal stress acting perpendicular to the line of the weld and the shear stress acting parallel to the weld.
