고체역학 (Beer) — Transformations of Stress and Strain: Problem 7.134

7.132 through 7.135 For the given state of plane strain, use Mohr’s circle to determine the state of plane strain associated with axes x' and y' rotated through the given angle \(\theta\). 7.130 and 7.134: \(\epsilon_x = -500 \mu\), \(\epsilon_y = +250 \mu\), \(\gamma_{xy} = 0\), \(\theta = 15^\circ \uparrow\) (Counterclockwise)
