Abstract
The utility model belongs to the field of physical teaching aids and particularly relates to a ruler for measuring arm of force. The ruler is characterized in that a graduated ruler A is connected to the fulcrum part of a lever through a pin shaft; and a chute is formed on the graduated ruler A, and the graduated ruler A is fixed with a graduated ruler B perpendicular thereto through a bolt. Therefore, the utility model has the advantages of simple structure, capability of measuring arms of forces in different directions, and accurate experiment conclusion.
Description
Technical field: the utility model belongs to physics teaching apparatus field, is specifically related to a kind of dynamometry arm chi.
Background technology: physics is a subject based on experiment, many notions, law all prove by experiment in physics teaching material, especially in mechanics teaching, during the research lever equilibrium condition, need to measure the arm of force of different directions power, and existing lever can only be measured the arm of force of vertical direction power, the arm of force of other direction power all can't be measured, cause experimental data to be restricted, the conclusion that must get is not very accurate.
Summary of the invention: the purpose of this utility model provides a kind of simple in structure, can measure the arm of force of different directions power, and experiment conclusion is dynamometry arm chi accurately.
The technical solution of the utility model is: a kind of dynamometry arm chi, form by chassis, support and lever, support one end and chassis are affixed, the other end matches with lever by fulcrum, it is characterized in that: the balance pivot place connects the A rule by bearing pin, establishes chute on the A rule by the perpendicular B rule of bolt.
Owing to adopt technique scheme, on lever, be provided with two vertical scale chis, can be positioned at any side of lever as required, angle also can be adjusted, and can measure the arm of force of different directions power, scope of experiment and final conclusion foundation have been enlarged, solved the original arm of force limitation that can only measure vertical direction power, be convenient to that the student understands and grasp principle and teacher's effect of teaching, thereby have simple in structure, can measure the arm of force of different directions power, experiment conclusion is advantage accurately.
Description of drawings: come the technical solution of the utility model is described in further details below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
Embodiment: with reference to the accompanying drawings.A kind of dynamometry arm chi, be made up of chassis 8, support 7 and lever 3, support 7 one ends and chassis are affixed, and the other end matches with lever by fulcrum, connect A rule 1 at lever 3 fulcrum places by bearing pin 6, establish chute 4 on the A rule 1 by bolt 5 fixing perpendicular B rules 2.
