P5.22 Two axial members are used to support a load P = 72 kips as shown in Fig- ure P5.22. Member (1) is 12 ft long, has a cross- 55° sectional (1) A1 1.75 in.2, and is made of area В A structural steel [E 29,000 ksi]. Member (2) is 16 ft long, has a cross- sectional area of A2 4.50 in.?, and is made of an aluminum alloy [E= 10,000 ksi]. V P FIGURE P5.22 (a) Compute the normal stress in each axial member. (b) Compute the deformation of each axial member. (c) Draw a deformation diagram showing the final position of joint B. (d) Compute the horizontal and vertical displacements of joint B.
