Embodiment Construction

[0010] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, the demonstration device for conservation of angular momentum in this embodiment includes a base 1, a main shaft 2 rotatably mounted on the base 1, and a telescopic assembly installed on the upper end of the main shaft 2. A motor 3 for driving the main shaft 2 to rotate and a detection system are installed in the base 1. The detection processor 4 of the angular velocity of the main shaft 2, the detection processor 4 can calculate and display the moment of inertia, angular velocity and angular momentum of the main shaft 2; 1. The upper telescopic head 6 and the lower telescopic head 7 are movably sleeved on the main shaft 2. The upper end of the upper telescopic head 6 is fixed with an upper anchor angle 8, and upper support arms 9 are movably installed on both sides of the upper anchor angle 8. The upper anc...

Abstract

The invention relates to a presentation device for angular momentum conservation, comprising a base, a main shaft rotationally installed on the base and a flexible assembly installed at the upper end of the main shaft, wherein a motor driving the main shaft to rotate and a detection processor detecting the angle speed of the main shaft are installed on the base; the flexible assembly comprises a flexible driver fixed at the upper end of the main shaft as well as an upper flexible end and a lower flexible end installed at the upper and lower ends of the flexible driver and movably sleeved on the main shaft, the upper end of the upper flexible end is fixedlyinstalled with an upper anchoring angle, an upper support arm is movably installed on the upper anchoring angle, the lower end of the lower flexible end is fixedly installed with a lower anchoring angle, a lower supporting arm is movably installed on the lower anchoring angle, the upper end of the lower supporting arm is hinged with the lower end of the upper supporting arm, and the lower end of the upper supporting arm is provided with a heavy ball. With rational structure design, simple structure and convenient use, the presentation device can help students know and understand angular momentum conservation rule, and the teaching demonstration of teachers are convenient.

Description

technical field [0001] The invention relates to a demonstration device for conservation of momentum, in particular to an experimental device which can directly demonstrate the law of conservation of angular momentum. Background technique [0002] When the system is not subjected to external torque or the resultant external torque is zero, the angular momentum of the system will remain a constant. At present, there is no experimental device that can directly demonstrate the law of conservation of angular momentum. Contents of the invention [0003] In view of this, the applicant conducts research and design to provide a demonstration device for conservation of angular momentum, which can directly demonstrate the law of conservation of angular momentum, which is beneficial to students' understanding and convenient for teaching. [0004] In order to solve the above problems, the present invention adopts the following scheme: [0005] A demonstration device for conservation ...
