                Subject:        Q:spring constant calculation

                Does anyone know the equation (or the reference where it can
be found)
                that can be used to estimate a spring constant of a thin
plate (such as
                microcantilever) based on the plate geometry (thickness,
width, length)
                and Young's modulus of the material ?


                You help will be much appreciated.
