The state of plane stress at the surface of a column is represented on the stress block shown in Figure 1. Solve the problem using stress transformation equations. a. Determine the state of stress of the stress block when oriented at an angle of X3 from the positive x axis. Show your results on the stress block. b. Determine the state of stress of the stress block when oriented at an angle of X3 from the positive x axis and consider the normal stress X2 to be zero. Show your (20%) results on the stress block.
