NOTE: There is a typo for max shearing stress and max shearing strain. For the third case of max shearing stress, where σp1 and σp2 have the same signs, the equation (0 - σp2 / 2) is for the case where | σp1 | < | σp2 |. Similarly for the third case of max shearing strain, where εp1 and εp2 have the same signs, the equation ( 0 - εp2 ) is for the case where | εp1 | < | εp2 |. Please make a note of this! Additionally, the third condition for max shearing strain should equal 0 - εp2, NOT εp3. Problem Begins at 5:50. Thanks for watching and supporting!
