Abstract
In the previous paper1), the authors analyzed the elastic deformation of a single flat spring fulcrum used in scales theoretically, made it clear that the elastic curves are expressed by hyperbolic functions, and obtained the relationships between the inclination angles, φ at the upper end and ψ at the lower end, of the elastic curve.
In this paper, the authors discuss on the experimental verification of the theoretical analysis made in the previous paper1), and on practical application of the analysis in part.
It is qualitatively verified that the shape of the flat spring is expressed by hyperbolic functions from the photographs of the flat spring which is deformed by the metal blocks applied at the lower end of the spring, the shape of which depends on the position of the center of gravity of the metal blocks.
To examine the relationships between the inclination angles more quantitatively, the authors measured the values of ψ coresponding to φ which is varied from -0.1 to +0.1 rad.
The agreement between the theory and the experiment is satisfactory.
