Abstract
The utility model discloses a physical measurement tool, particularly a spring balance which can directly reflect the length of deformation of a spring and can be used for experiments. The spring balance with deformation scales has structure that a quality and force scaling panel of a pulling type spring balance is additionally provided with a scaleplate. The utility model is used, which can conveniently directly complete the physical experiments for verifying Hooke's law and measuring the coefficient of stiffness of the spring and can cause errors to be reduced.
Description
Affiliated technical field
The utility model belongs to the physical measurement instrument, particularly the direct experiment spring balance of measuring spring deformation length.
Background technology
The experiment of checking Hooke's law and measuring spring stiffness factor is arranged in physics teaching, its theory is in elastic limit, and the elongation x of spring is directly proportional at the suffered external force F of prolonging direction with it, Here it is Hooke's law, its expression formula is: F=kx, scale-up factor k are the stiffness factor of spring.It is essential with spring balance and independent rule to do when experiment, take rule repeatedly the measuring spring scale be subjected to external force deformation length, inconvenience and error are big.
Summary of the invention
The purpose of this utility model provides the technical scheme that the direct measuring spring scale of a kind of energy is subjected to external force deformation extended length.
The technical solution of the utility model is that a kind of spring balance with the deformation scale is characterized in that: additional directly measuring spring scale is subjected to the scale of external force deformation extended length on the scale panel of the quality of the pull-type spring balance in laboratory and power.
Quality scale on the spring balance scale panel, power scale and deformation scale can organic convenient arrangements.
The beneficial effects of the utility model in the quality of energy measurement power and testee directly the measuring spring scale be subjected to the extended length of external force deformation.
