1.32. An aluminum right-circular cylinder surrounds a steet cylinder as shown in Fig 1-29. The axial compressive
load of 200 kN is applied through the rngid cover plate shown. If the aluminum cylinder is originally 0.25 mm
longer than the steel before any load is applied, find the normal stress in each when the temperature has dropped
20 K and the entire load is acting For steel take E = 200 GP a= 12x 10C. and for aluminum assume
E=70 GPa, a=25 x10 rCi
Ans 0=9 MPa, o155 MPa
