Abstract

The invention discloses a viscosity coefficient measuring system for teaching, which comprises a supporting device, a traction device and a measuring device, and is characterized in that the supporting device comprises a substrate, a U-shaped rail and a fixed pulley; the stepping motor pulls the metal ball to ascend and descend in a full-automatic mode, the tension sensor measures parameters such as the tension in real time, the viscosity coefficient of any liquid can be accurately calculated according to the measured parameters in combination with methods such as stress analysis, the Stokes law and error analysis, the measurement error is reduced, the automation degree is high, and the measurement accuracy is high. The defects of an existing measuring device are ingeniously overcome, automation of an experimental device is further improved, meanwhile, students can be helped to learn viscous force, buoyancy, stress analysis and other knowledge in physics, the students can also be taught to control a motor, use a micrometer caliper and other skills, the learning interest of the students is stimulated, and the experimental device is suitable for popularization and application. Students can conveniently explore the experiment essence.

Description

technical field [0001] The invention relates to the fields of physics teaching and electronic technology, in particular to a viscosity coefficient measuring system for teaching. Background technique [0002] At present, some experimental devices in the basic laboratory are developing in the direction of intelligence, diversification, integration, and strong teaching significance. In the previous experimental classroom, the experiment of measuring the viscosity coefficient of fluid by the falling ball method was limited by the influence of the experimental device. , the teacher can't show the experimental phenomenon in front of the students well, so that the students have certain obstacles and difficulties in the process of learning and understanding. The human eye observes the falling process of the metal ball, and cannot accurately judge whether the metal ball is moving in a straight line at a constant speed; in the experiment, the measuring cylinder containing the liquid...
