The figure shows the stresses at a point. Determine the principal stresses and the maximum shear stress. Show these values on the faces of properly oriented stress blocks.

For 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 MPa

Determine the average normal stress developed at points A, B, and C. The diameter of each segment is indicated in the figure.

At a point in a strained material the principal stresses are 200 N/mm2 (tensile) and 120 N/mm2 (compressive). Determine the normal stress, shear stress and resultant stress on a plane inclined at 30° to the axis of major principal stress. Also determine the maximum shear stress at the point.
