Question

Shown in the figure below is a solid cylinder. The x-axis is along the longitudinal direction. The angle is measured with respect to the x-axis, positive if counterclockwise, i.e. towards the y-axis as shown below; and negative if clockwise. 01 and 02, with are the principal stresses, and Imax is maximum shear stress. 01202 Fracture surface Normal to Fracture surface Suppose that the cylinder is subjected to a uniform tensile stress of 5000 psi in the longitudinal direction. The orientation () for Tmax is: O 30° 45° O 0° 90°
