Trying to study this question on stress transformations and mohr's circle and am having some difficulty
The state of stress at a point is defined by sigma x = -30 MPa, sigma y = 20 MPa, and tau xy = 15 MPa. 1) Draw the Mohr’s circle and label the key features (e.g., sigma 1, sigma 2, tau max, theta p1, and theta p2). 2) Draw the element showing the principal planes, principal stresses and principal directions with proper labels. 3) Determine the normal and shear stresses on a plane inclined at alpha (degrees) = 30 to horizontal turned anticlockwise. Show the procedure in the Mohr’s circle, with proper labels.
