Problem-1 Use the plane stress transformation equations to find the normal stress and the magnitude of the shear stress on plane A-A for the stress acting at a point in a machine component shown below. Problem-2 . Find the principal stresses and the maximum in-plane shear stress for the stress condition acting at a point in a machine component shown. Problem-3 Show a Mohr's Circle plot depicting the principal stresses and the maximum in-plane shear stress for the stress condition acting at a point in an engineering structural member. Use the graphical method, and a tool to validates the process (as shown in class). 35 80MPa 80MPa yx 80MPa 80MPa 110 MPa 110 MPa T =55 MPa xy 115 MPa Lyx =55 MPa xy 115 MPa xy-70 MPa 165 MPa
