One Answer

For same shearing stress if absolute value of sigma_x-sigma_y is larger, points on Mohr circle are wider apart and R is larger thus maximum shear stress is larger. Variable u is introduced to represent this connection and derivative was tried to obtain solution but it failed and solution was obtained using geometric properties of Mohr's circle. You should try to draw circle for better understanding.
