300 m Brass core E-105 GP Alum shell K-70 CP 2.33 An axial force of 200 kN is applied to the assembly shown by means of rigid end plates. Determine (a) the normal stress in the alumi Een shell, (b) the corresponding deformation of the assembly. 2.34 The length of the assembly shown decreases by 0.40 mm when an sxial force is applied by means of rigid end plates. Determine (a) the magnitude of the applied force, (b) the corresponding stress in the brass core. 2.35 A 4-ft concrete post is reinforced with four steel bars, each with a in diameter. Knowing that E, 29 x 10 psi and E, 36 x 10 psi. determine the normal stresses in the steel and in the concrete when a 150-kip adal centric force P is applied to the post. Fig. P2.33 and P2.34
