1. The problem statement, all variables and given/known data Hi everyone. I need to do project on a 4-legs square table of dimensions 0.5m*0.5m*0.5m with weight X newtons. At each corner, there is a column supporting the table. A downward force of 150 Newtons will act on the table at the place where one of the column is. Before handing in the project, I need to calculate the force acting on each column. However, I can only give 3 equations with 4 unknowns. 2. Relevant equations 3. The attempt at a solution I tried using similar triangle that formed by the deflections of the four legs to solve the problem but I failed since no unknowns could eliminate from the equations. Thanks in advance for any efforts to show me how to do this P.S. I am a Hong Kong student studying materials engineering so my English isn't very good. If there is any grammatical mistake, please ignore it.
