(b) A short post AB constructed from a hollow circular tube of aluminium, supports a compressive
load of 116 kN as in Figure Q2 (b). The inner and outer diameters of the tube are di=100 mm and
dz=112 mm, respectively, and its length is 400 mm. The shortening of the post due to the load is
measured as 0.3 mm. Determine the compressive stress and strain in the post.
Note: the weight of the post is neglected.
