1. Element A is subjected to the stress state shown in the x-y plane (+x is to the right, +y is up). Use Mohr's Circle to solve the following problems. You MUST draw Mohr's Circle to get credit for these problems! (a) Determine the complete state of stress on the element in the x-y coordinate system. (b) Determine the state of stress if this element is rotated 25° clockwise. 75 MPa Answers: (a) ox 105 MPa (T); oy 75 MPa (1); txy=+25 MPa; 0₂= Txz=Lyz = 0 (b) ox 118.8 MPa (1); y = 61.21 MPa (T); txy = -4.579 MPa (c) 01.2 119.2 MPa (T), 60.8 MPa (1) (d) Tmax.in-plane 29.15 MPa (e) Tmax.absolute == 59.58 MPa; no, Tmax absolute is not in the x-y plane All three circles must be drawn for part (e)! 25 MPa (c) Determine the values of the principal stresses. (d) Determine the value of the maximum in-plane shear stress, Tmax in-plane- (e) Determine the absolute maximum shear stress, Tmax absolute (by drawing circles from each principal stress to the origin). Is Tmax absolute in the x-y plane (i.e., is Tmax,absolute equal to Tmax.in-plane)? 105 MPa
