Integrated experimental instrument for composition and decomposition of forces on inclined planes

Abstract

The invention relates to an integrated experimental instrument for the composition and decomposition of forces on inclined planes, which is an experimental apparatus in teaching laboratory and physicslaboratory equipment. The integrated experimental instrument solves a problem that the traditional instruments cannot measure accurately because of the adoption of a spring scale for force measurement, and further realizes functions, which are not possessed by the traditional instruments, of directly displaying a force measurement value on equipment and transmitting the value to a computer in a wired or wireless mode so as to display a continuous force measurement curve on a computer screen. The integrated experimental instrument innovatively adopts the technological paths such as an integrated structure design, a force measurement strain gauge, relevant electronic circuits and computer software, realizes continuous measurement for the vertical pressure of two inclined planes when the included angle between the inclined planes and the horizontal plane continuously changes between 0 degree and 90 degrees, and displays a measurement curve on the computer screen, thereby synchronously verifying the composition and decomposition principles of forces on the inclined planes.

Description

technical field [0001] Experimental equipment in teaching laboratories and physical experiment equipment. Background technique [0002] The "decomposition of force on an inclined plane" experimental instrument in the existing teaching laboratory and physical experiment equipment uses a spring balance as a measuring device for testing. Place the object to be measured on the experimental instrument, adjust the angle, read the magnitude of the two forces through the reading of the spring balance, and then draw points on the paper to verify the decomposition principle of the force on the slope. Due to the low precision of the spring balance used in this experimental instrument, there are errors in the principle verification. Coupled with the inability to continuously measure and automatically read data, and the inability to use computers to assist teaching, it has become backward and inapplicable in today's highly developed computer and automatic control technology.
