I have a question about load cells.
I tried to find a load cell to measure forces and moments in x, y and z directions of a steel columns. Since the strength of the column is huge, so purchasing a load cell with large loading capacity is very expensive. So, i am thinking a possible solution. I just put the strain gages at the root of the steel column. By special setup of the strain gage, i can tell the forces and moments of the column. So, the column itself is a load cell.
Maybe it does not have to be the steel column. I can use another piece of the steel piece with strain gage on, then connect this piece with the steel column, which i want to test.
Does anyone has thus experience before? I know there have several potential problems. However, do you think if it is doable? Any suggestion is appreciated.
