problem. 1 The state of plane stress at a point is described by stress measurement made at three separate orientation as indicated in the diagrams of Fig.1. Your task is to determine 1. da, dy and Tay when 0 = 0. For full credit, solve the resulting equations by hand 2. The maximum principal shear stress (1.e.,7mar), and the associated element orientation measured with reference the horizontal axis (i.e.,) Roughly draw a Mohr circle - On the circle identify the state of stress at 0-0 (a.. Tay) The point of maximum shear stress (i.e.,7mas )and the angle (2 ) with reference to state of stress at 0 Use appropriate trigonometric relation and solve for (4) dx 9-65 830 8=0 Figure 1: at 0=0° 0 = 24 MPa at 0 = 30° Ta"y"=35 MPa at 8 = 65° y = 15 MPa
