Abstract
The utility model relates to a device which can instantaneously display the tensile force applied by a rope when a simple pendulum swings and count the swinging times of the simple pendulum. According to the utility model, by fixing a pressure inductor at the upper part of an outer frame, the tensile force of a simple pendulum ball applied by the rope can be measured and displayed instantaneously; and by fixing electronic counter devices at the left and right sides respectively, the swinging times of the simple pendulum can be counted, so that students can research the simple pendulum movement situation more effectively.
Description
Affiliated technical field
The utility model belongs to a kind of physics and probes into experiment teaching aid, can be used for demonstrating the stressing conditions of single pendulum and calculates the single pendulum frequency.
Background technology
In junior middle school's teaching, can relate to the problem of relevant single pendulum, and can not demonstrate out the stressing conditions of single pendulum at present intuitively or can make the student more directly simply calculate the demonstration teaching aid of single pendulum frequency.
Summary of the invention
The utility model technical issues that need to address are a device that can show the pulling force size of single pendulum suffered rope when swing immediately and can calculate single pendulum number of oscillations in a period of time.
The utility model solves the technical scheme that its technical matters adopted: one can be upright the fixing pressure inductor in housing top; The pulling force of the suffered rope of single pendulum bead can measured and show to pressure inductor immediately; Fixing electronic counting apparatus in the framework left and right sides; This device can calculate the number of times that single pendulum is put, and just can calculate the frequency of single pendulum through this device.
The beneficial effect of the utility model is: can manifest the suffered pulling force situation of single pendulum bead immediately; Make the student understand intuitively single pendulum in each position suffered tension variations situation; Can calculate the number of times that single pendulum was put in a period of time through the electronic counting apparatus; The function that has the stressed situation of change of demonstration single pendulum simultaneously and calculate the single pendulum frequency makes the more effective motion conditions of probing into single pendulum of student.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model, and wherein 1 is pressure inductor, the 2nd, and rope, the 3rd, electronic counter right portions, the 4th, bead, the 5th, housing, the 6th, electronic counter left part, the 7th, base.
Embodiment
In the drawings; Pressure inductor 1 is fixed on the housing 5, bead 4 is connected with pressure inductor 1, respectively electronic counter left part 6 and electronic counter right portions 3 are fixed on housing 5 left and right sides with rope 2; Base 7 is connected with housing 5; Play the effect of stabilising arrangement, when bead 4 swing, but pressure inductor 1 just instant playback go out the suffered pulling force situation of bead 4; Rope 2 number of times during through the centre position in a period of time can calculated and demonstrate in electronic counter left side 6 and electronic counter right side 3, just can make the student can calculate the frequency of single pendulum easily.
Claims (1)
1. physics inquiry experiment teaching aid; It is characterized in that fixing pressure inductor on housing top; Just can measure and show the pulling force of the suffered rope of single pendulum bead immediately; Fixing electronic counting apparatus just can calculate the number of times that single pendulum is put in the framework left and right sides, the function that has the stressed situation of change of demonstration single pendulum simultaneously and calculate the single pendulum frequency.
