- The state of stress at a point on an element of material is shown. Let sigmaX= 49.0 ksi, sigmaY= 17.0 ksi, and Txy= 11.0 ksi. Use this information to represent the principle state of stress and maximum in plane shear stress. Plot the mohr circle and state sigmaX' and sigmaY' and Tx'y' with unit. Also draw the state of stress on the rotated element.arrow_forwardFor the element shown below, determine: 1- The principal stresses and the maximum in-plane shear stress acting at the point by using equations, then show these stresses on an appropriate sketch. 2- The normal stresses 0 n and ¢ t and the shear stress T nt for element oriented 20° clockwise from the position shown, using Mobhr’s Circle. 75 MPaarrow_forwardDraw the Mohr’s circles.
