I have an application where I am trying to figure out the shock load being applied to a metal pin (load cell).
It is a cylindrical load cell which is supported at either end, and compressed in the middle. There is a slight gap between the end supports and the section compressed in the middle, this provides shear force across two planes which is measured by strain gauges.
In our situation we know the output from the strain gauges at 500Kg shear force, but the output at 0kg is becoming offset after use, and I need to try and figure out how much force is being applied to create this offset.
I don't really know where to start, but in my reading so far it seems like if I could treat the pin as a simply supported beam I might be able to make a start. So back to my question, can a cylindrical pin be considered as a simply supported beam?
thanks
