A thin flexible metal plate attached at one end to a platform, as shown above, can be used to measure mass.When the free end of the plate is pulled down and released, it vibrates in simple harmonic motion with aperiod that depends on the mass attached to the plate. To calibrate the force constant, objects of known massare attached to the plate and the plate is vibrated, obtaining the data shown below.
