From the state of stresses on a stress element as shown. - Find the state of stresses on the plan AB. - Find the state of stresses when the stress element is rotated clockwise by 30 by using the equations and Mohr's Circle and draw the associated stress element. - Find the state of principal stresses and max. in-plane shear stresses by using the equations and Mohr's Circle and draw the associated stress elements. A steel structural member as shown is subjected to 6 kN force. Determine the state of stresses at point B. Find the state of principal stresses and max. in-plane shear stresses at point B by using the Mohr's Circle and draw the associated stress elements.
