Abstract
In this paper similarities between threeforce and threepoint nonsmooth optimization problems are highlighted Starting from geometrical rules controlling discrete optimum solutions for threepoint problems a reasonable hypothesis is created for similar geometrical rules to control discrete optimum structures for threeforce problems The hypothesis is confirmed through a numerical approach A stepbystep method to graphically obtain a discrete optimum structure for any set of three balanced forces is provided It is shown that discrete optimum structures with large number of elements converge to the known continuum optimum solutions in the literatureI would like to thank William F Baker of Skidmore Owings and Merrill LLP and Dr Cenk Tort of Mitaş Engineering for continuing support and advice Without these two individuals writing this paper would not be possible Also I would like to thank Prof G H Paulino Ms L Stromberg and the rest of the TOP Gang at University of Illinois in Champaign who are the experts in the field of topology optimization for their valuable suggestions and opinions
