Abstract
The utility model provides a testing device for decomposing the force on the incline, which comprises an angle graduated scale, a base, a bracket, a heavy supporting stage and a force sensor; the angle graduated scale is fixedly arranged on the base, one end of the bracket is hinged with the base and another end is connected with the angle graduated scale, the strain gauge of the force sensor is arranged on the bracket, the heavy supporting stage is arranged on the strain gauge of the force sensor. When in use, the force sensor is connected with the external data collector, the annular heavy is arranged on the strain gauge of the heavy supporting stage, the sensor is able to measure the stressed value of the heavy in different angles by adjusting the angle of the bracket, the data colleted by the data collector is displayed by the computer. The utility model has the advantages of simple structure, simple operating, automatically data collection, high sensitivity, and small error which can be controlled in five percent.
Description
Technical field
The utility model relates to and is used for the experimental apparatus that power is decomposed on the inclined-plane in the teaching, belongs to technical field of teaching instruments.
Background technology
At present in middle school teaching on the inclined-plane resolution of force can only be undertaken by the weight beam weight of slinging, the bad control in angle of inclination, read untrue, inconvenient operation, experimental error is big.Demonstration during experiment and all very inconvenience of explanation.
Summary of the invention
The utility model provides resolution of force tester on a kind of inclined-plane simple in structure, easy to use at the deficiency of in the existing teaching power on the inclined-plane being decomposed the technology of experiment.
For achieving the above object, the utility model adopts following technical solution:
The resolution of force tester comprises angle index chi, base, support, weight cushion cap and force transducer on the inclined-plane, the angle index chi is fixedly mounted on the base, support one end is hinged on the base, the other end is connected on the angle index chi, the strainometer of force transducer is rack-mount, and the weight cushion cap is installed on the strainometer of force transducer.
During use, the data acquisition unit of force transducer with the outside connected, and annular weight is placed on above the weight cushion cap of support, regulates the angle of support, can measure the stress value of weight when the different angles by force transducer, after the data acquisition unit image data by the computing machine video data.
The utility model is simple in structure, manipulate simple, can automatic data collection, sensitivity is higher, error is little, can be controlled in 5%.
