Prandtl's membrane analogy is useful for solving some problems of elasticity. Since the material, approaching the properties of a membrane that has been used in the past is soap film, this analogy has been difficult to apply due to instability of the membrane. In order to overcome this instability problem, plastic films have been investigated. Application of this analogy is made to a problem with a known solution using different membrane materials and different methods of measurement. The apparatus and technique in using plastic film in Prandtl's membrane analogy is described and the inherent error of a plastic film membrane is discussed.
