Question 1: The general state of stress at a point is characterized by six independent normal and shear stress components which act on the faces of an element of material located at the point. Show a schematic view of the general state of stress. Using Mohr’s circle, determine the principal stresses of an element having σx = 45 MPa, σy = 55 MPa and ?xy = 25 MPa. Show them on a sketch of a properly oriented element. Using Mohr’s circle, determine the maximum and minimum shear stresses. Show them on a sketch of a properly oriented element. Determine the equivalent state of stress if the element is oriented 30º clockwise by using Mohr’s circle. Show them on a sketch of a properly oriented element.
