Determine (a) the principal stresses and (b) the maximum shear stress and associated normal stress at the point in Figure 4. Specify and sketch the orientation of the element in each case. The directions of the stress components are as indicated in Figure 4. 100 MPa 200 MPa 300 MPa

A structural member is subjected to the plane stress condition. The state of stress at a point of the member is shown in the figure. 45 MP (1) Draw the Mohr's circle for this 2D state of stress. (2) Determine the principal stresses, the maximum in-plane shear stresses and associated normal stresses acting at this point, (3) Represent these critical stresses on new stress elements, and indicate the angles of rotation of the new stress elements with respect to the original stress elements. 25 MP

Find the interal normal stress in all relevant segments of the bar in the picture.

The stresses shown in Figure below and act at a point on the free surface of a machine component. Determine the normal stresses σ x and σ y and the shear stress τ xy at the point.
