Part 1 Consider a point in a structural member that is subjected to plane stress. Normal and shear stresses acting on horizontal and vertical planes at the point are shown. Assume stress magnitudes of 5 = 180 MPa. S = 130 MPa, and Syy = 70 MPa. B = 60. Construct Mohr's circle for this state of stress on paper and use the results to answer the questions in the subsequent parts of this GO exercise. For this Mohr's circle, point x, which represents the state of stress on the x face of the stress element, should appear: O Below and to the right of the circle center. Above and to the right of the circle center. O Below and to the left of the circle center. O Above and to the left of the circle center. Save for Later Attempts: 0 of 1 used Submit Answer

(a) Determine the magnitude of the maximum in-plane shear stress. (b) Determine the normal stress that acts on planes of maximum in-plane shear stress. Give the stress value including sign if any. Answers: (a) Tmax = MPa. (b) Gave = i MPa Save for Later Attempts: 0 of 1 used Submit Answer Part 7 To determine the normal and shear stresses on the indicated plane, we must first determine the orientation of the inclined plane relative to the x face of the stress element. Determine the magnitude of the counterclockwise angle between the x face and the inclined plane Assume p = 60,5 = 180 MPa. S = 130 MPa and Soy = 70 MPa. 1 Answer: 0 = i
For Mohr's circle, all angular measures are doubled; therefore, point n (which represents the state of stress on the plane) on Mohr's circle is rotated 20 counterclockwise from pointx. From the Mohr's circle that you constructed on a piece of paper, determine the smaller central angle | between point n and the principal stress (p2.
