| Abstract: | Base on the experiment of Young＇s modulus, in which the metal wire is measured by the tensile method, the improved laser optical lever is applied to the human weight mea- surement. According to linear relation between the displacement and mass, the laser straight CCD weighing machine is made, and the human mass is shown on the liquid crystal display by data acquisition and processing. The measurement results show that the accuracy of the hu-man mass can achieve 0. 01kg. This work broadens out the application range of Young＇s mo-dulus, inspires the divergent thinking of students, and links the physics experiment to the li-ving practice tightly. |
