10 kN at its tep. Find the minimum diamete11equired if the post is'of wood, if the permissible bending
stress is 15 N/m1112. Alternatively, if a hollowaluminum tube whose thickness isone eighth of the
external diameter, is provided, what would be the external and internal diameters of the tube?
Pennissihle bending stress for aluminum is 50 N/mmz.
