An element of aluminum in triaxial stress (see figure) is subjected to stresses σx= 5200 psi (tension), σy= -4750 psi (compression), and σz= - 3090 psi (compression). It is also known that the normal strains in the x and y directions are x= 713.8 × 10-6 (elongation) and y = - 502.3 × 10-6 (shortening). What is the bulk modulus K for the aluminum?
