Problems solved by technology

However, in the course of the experiment, when the students release the pendulum ball with their hands, the "cone pendulum" often appears due to the force of the hand on the pendulum ball other than the gravity and the cycloid pull force, which does not meet the theoretical requirements of the single pendulum experiment. Bring large error to the experiment

Embodiment Construction

[0009] exist figure 1 Among them, three foot screws 14 are installed on the side of the table at the bottom of the base 1 to adjust the verticality of the vertical rod 2 to adjust the balance state of the cycloid 5 . The upper part of the base 1 is screwed to install the vertical rod 2, and the upper end of the vertical rod 2 is fitted to install the hanger 3, and the hanger screw 4 is installed on the hanger 3, and the height of the hanger 3 can be adjusted by loosening and tightening the hanger screw 4 . The upper end of cycloid 5 is installed on the hanger 3 (also can increase the hoisting screw of adjusting cycloid length to facilitate the adjustment of the length of cycloid 5). The lower end of the cycloid 5 is connected with a pendulum ball 6 made of steel or iron. The short side of the support 7 is fitted with the vertical pole 2, and is adjustable on the vertical pole 2 through the elastic bracket screw 8, so that the height of the support 7 can be adjusted to meet t...

Abstract

The invention discloses a single pendulum experiment instrument. The single pendulum experiment instrument comprises a base and bottom foot screws, wherein the upper part of the base is provided witha vertical column; the upper end of the vertical rod is provided with a hanging bracket; the hanging bracket is provided with a hanging bracket screw; the upper end of a cycloid is mounted on the hanging bracket, and the lower end of the cycloid is connected with a swing ball; a bracket is adjustably mounted on the vertical rod through a bracket screw; an electromagnet movable bracket is arrangedon the bracket in a sleeving manner; an electromagnet is mounted on the electromagnet movable bracket; and the electromagnet and a power supply are electrically connected with each other. The single pendulum experiment instrument overcomes the defect that a single pendulum experiment instrument in the prior art is prone to conical pendulum during the experiment process, and the experiment precision is improved. The single pendulum experiment instrument can be used for the single-pendulum experiments in college physical experiments.

Description

technical field [0001] The invention relates to a physical mechanics experiment device, in particular to a simple pendulum experiment instrument. Background technique [0002] The simple pendulum experiment is an experimental project that is often done in the physics experiments of various colleges and universities in China. In the prior art, the experimental device includes a base and a vertical rod fixed on the base, the upper end of the vertical rod is fixed with a hanger, and the iron pendulum ball is hung on the hanger with a very thin light wire rope , and then pull the pendulum ball to a certain small angle (less than 5 degrees) by hand, and let the ball swing freely back and forth, which forms a simple pendulum. Then use a stopwatch or a special photoelectric gate to cooperate with a period measuring instrument to collect the period T, and then measure the length of the cycloid and the diameter of the pendulum ball to calculate the pendulum length L, then you can us...
