A 3-m-long steel [E = 200 GPa] tube supports an eccentrically applied axial load P as shown in Figure P16.47/48. The tube has an outside diameter of 75 mm and a wall thickness of 6 mm. For an eccentricity of e = 8 mm, determine

(a) the load P for which the horizontal deflection midway between A and B is 12 mm.

(b) the corresponding maximum stress in the tube.
