40 B T (MPa)) 10 Y 0 C F A (MPa) 20 R X -50- 40 Answer the following for the Mohr's circle shown above: 1. Draw the state of stresses on the original element represented by XY plane 2. Calculate the principal stresses, then draw the transformed element at this state 3. Calculate the maximum shear stress, then draw the transformed element at this state 4. What is the state of stresses at a plane oriented 30 clock wise from the element shown?
