Combined Stresses
Note: The complete solutions for problems 10-56 10-105 require the constructions of the
stress element. Listed below are the significant numerical results. Following the list are the
representative examples of the complete solutions. Note that the problems fall into groups of
similar forms as described below.
A. Problems 10-56 to 10-59: The x- 1st quadrant.
Problems 10-60 to 10-63: The x- 2nd quadrant.
B. Problems 10-84 to 10-95: results in both
principal stresses having the same sign. For this class of problems, the
Combined Uniaxial Normal and Shear Stresses
Problems 10-106 to 10-109: These use the same data as Problems 10-72 to 10-75 and each
has a given uniaxial stress, and a shear stress, . For this special case, Equation 10-2 can
