AI Technical Summary
Traditional methods for measuring the Young's modulus of metal wire and the coefficient of linear expansion of metal rod require two different measuring instruments, resulting in a waste of laboratory space and equipment costs. Furthermore, the optical lever experiment is complex to operate and inconvenient for teaching and student experiments.
A magnetic grating sensor measurement system is adopted, including a support assembly, a fixing mechanism, a sliding mechanism, and a magnetic grating sensor. The magnetic grating sensor measures the tensile amount of the metal wire or the expansion amount of the metal rod. Combined with a heating device, a comprehensive experiment is achieved, reducing equipment and space occupation.
It enables convenient measurement of Young's modulus of metal wire and coefficient of linear expansion of metal rod, simplifies experimental operation, reduces equipment cost and space requirements, and is suitable for teaching and student experiments.
