The reference state of stress shown in the element sketch below results in the Mohr’s circle plot indicated. For this element, as described below, determine:a)The principal stresses.b)The principal directions (angles to the principal planes).c)The maximum in-plane shear stress.d)Is the maximum in-plane shear stress the absolute maximum shear stress?

Solve show all steps

Solve parts (a) to (c) using transformation equations only (not Mohr's circle), and show the complete state of stress with the appropriate stress element properly oriented relative to the given xy coordinate system. Given the state of plane stress shown, (a) determine the state of stress for an element oriented 20° clockwise relative to the given xy coordinate system. (b) determine the state of stress for the element containing the principal stresses. (c) determine the state of stress for the element containing the maximum in- plane shear stresses. (d) determine the state of stress for the element containing the maximum shear stresses. (e) draw Mohr's circle indicating the states of stress and angular orientation found in parts (a) to (c). - 8 MPa 40 MPa 12 MPa x
