Abstract
The utility model relates to an elasticity coefficient experimental instrument device for springs connected in series. The instrument device is used for teaching auxiliary experiment. A first pulling-type digital electronic scale (6), a first spring (4), a second pull-type digital electronic scale (7) and a second spring (9) are hanged in series on a hanging rod of the support (12) with hooks. Each of the two ends of each spring is provided with a pointer. The instrument device provided with the utility model can be used for conducting the elasticity coefficient experiment for springs in series and the Hooke's law experiment for the springs. The pulling force of each spring of the combined springs can be read out directly. The experiment method is simple and direct, and the calculating formula of the elasticity coefficient of the combined springs can be understood conveniently. Since the digital electronic scales can be zeroed, the influence of the self-weight of the springs to the measuring precision can be eliminated and the measuring error can be reduced.
Description
Technical field:
The utility model relates to the elastic coefficient experimental apparatus device, particularly serial spring elasticity coefficient experimental apparatus device.
Background technology:
Spring is now applied to industry, space flight and domestic life field at large, and it is very tiny that spring has, and must take magnifier, and such as the spring on clock and watch, what have is very large, even people all remove motionless, such as blocking water despot's generator equipment series.Because spring application prospect is good, also very deep to the research of spring, such as single spring, the mathematic(al) representation of Hooke's law is F=KX, and wherein F is the suffered pulling force of spring, and X is the length that spring extends, the elasticity coefficient that K is spring.To common people, particularly middle school is said from birth, the relatively good understanding of single spring Hooke's law, and experimental technique is also simple.Concerning cluster spring, the elasticity coefficient computing formula of serial spring be 1/K=∑-
1/ K---
1,it is large that this makes many students understand difficulty, and its experimental technique is also more complex.
Summary of the invention:
The purpose of this utility model is to provide a kind of serial spring elasticity coefficient experimental apparatus device, and it can carry out the elasticity coefficient experiment of serial spring, and its experimental technique is simple, directly perceived.
Technical solution of the present utility model is, comprise that the first tensile force type digital and electronic claims (6), the first spring (4), the second tensile force type digital and electronic to claim (7), the second spring (9) and successively by in-line the hanging over together of hook under part separately, and be suspended in the hanger bar on support (12), the first spring (4) and the second spring (9) two ends are provided with pointer.
The utility model can accurately be measured suffered pulling force and the elongation of each spring in cluster spring.The utility model is the digital electronic weigher of all connecting on every spring, can its suffered pulling force of Measurement accuracy, all be fixed with a horizontal pointer at the afterbody of every spring, can obtain the elongation of spring by measuring the displacement in vertical direction of horizontal pointer.
The utility model has the advantages that elasticity coefficient experiment and the experiment of spring Hooke's law that can realize series connection, can directly read the pulling force of each spring in cluster spring, experimental technique is simple, directly perceived, is convenient to the understanding to cluster spring elasticity coefficient computing formula.Can be withered because of digital electronic weigher, can eliminate the impact that spring is conducted oneself with dignity on measuring accuracy, reduce measuring error.
