At a point on the free surface of a machine part (E = 214 GPa, G = 83 GPa), the state of the stress is illustrated in the figure below. For the given plane stress condition determine: Show the principal stresses and the max in plane shear stress and the average normal stress on an appropriate schematic

A rectangular column (blue color) is fixed to a rigid ground (brown color). As shown in the figure, the column is under two external loadings at C. Determine the state of stress at point K of the column and represent the stress components on a stress element.

There’s a force acting in the Y and Z direction

An element in plane stress is subjected to stresses: 0 = 85 MPa, o, = -30 MPa, and Try = 32MPa, as shown in the figure below. (1) Determine the principal stresses and show them on a sketch of a properly oriented element; (2) Determine the maximum shear stresses and show them on a sketch of a properly oriented element. 30MPA 85MPA 32MPа 1

A state of plane stress is illustrated in the stress element in Figure 3. (a) (b) 30 MPa Figure 3. 40 MPa 60 MPa y X Find the center, X and Y of the Mohr circle. Plot the Mohr circle using these points. From the Mohr circle, find the principal stress and the maximum shear stress. Indicate on the Mohr circle where these values are found.

For a plane stress state, in the original Oxy system we know the component Ox = 120 MPa and Txy = 60 MPa. After the element (see the left figure) is rotated counterclockwise by 45°, we know the stress component Txryı = -60 MPa in the new Ox'y' system (see right figure). Determine the two principal stresses and the absolute maximum shear stress (ra). y Oy Txıy! x' Txy Ox 45 х

The state of stress acting at a critical point on a wrench is shown in the figure. Determine the smallest yield stress for steel that might be selected for the part, based on the maximum shear stress theory.
