Q.

At a point in a steel member, the major principal stress is 2000 kg/cm2 and the minor principal stress is compressive. If the uni-axial tensile yield stress is 2500 kg/cm2, then the magnitude of the minor principal stress at which yielding will commence, according to the maximum shearing stress theory, is                         
A. 1000 kg/cm2 B. 2000 kg/cm2
C. 2500 kg/cm2 D. 500 kg/cm2
