EXAMPLE 1.1 AXIAL PRINCIPAL STRESSES
A cylindrical specimen of rock, 50 mm in diameter and 100 mm long is
subjected to an axial compressive force of 5 kN. Find:
1. the normal stress σnθ and shear stress τθ on a plane inclined at 30° to the radial direction;
2. the maximum value of shear stress;
3. the inclination of planes on which the shear stress τθ is equal to one-half τθmax.
