Demonstration Pulley Set
....
It is the anatomical form of plug-type resistance box used to demonstrate its basic structure and principle, and used as general constant resistance.
....
It consists of magneto-electric internal magnetic structure, meter and converter. It is used to measure power in the teaching demonstration and experiment of middle school physics and for teachers and students in normal colleges.
....
It is a light guide demonstration device using optical beam transmission made of optical fiber as sound transmission and image transmitting media, combining photoelectric effect and electronic technology and using AC power.
....
The programme of exercises enables familiarisation with six different drive implementation and analysis methods: understanding the brief and the drawing, assembly, setting, adjusting, testing, and making calculations. This laboratory system is used to introduce combined drives and their correct assembly. A robust tubular steel frame with a square profile and bearing elements provide the accuracy for the setting of precise gearing. The flexibility of the set-up and the modularity of the components simplifies experimentation and implementation of the students' own ideas. All the system components are kept ready to hand and well protected in a housing system.
....
It is used to demonstrate that liquid has pressure on the bottom of container and side wall, the pressure of liquid to container side wall increases with the depth, and the pressure of liquid to all aspects is equal at the same depth.
....
It is used to demonstrate reflection law and refraction law of light in middle school physics teaching.
....
It demonstrates that one object can take part in the composition of two different aspects at the same time, and draws motion track directly. It is used in movement composition experiments of physics teaching. Two componential movements are uniform linear motions, or one is uniform linear motion, another is change speed linear motion (accelerating or decelerating).
....
It is used to demonstrate experiment of plant photosynthesis, respiration and transpiration. It consists of transparent container, funnel, top head, test tube, test tube rack and gas collecting cap.
....
It is used with electronic stopwatch and counter to study quantitatively vibration period is not connected with amplitude when the simple pendulum vibration declination is less than 5 degrees, that is isochronous; to study simple pendulum motion period is proportional to square root of pendulum length; to study simple pendulum vibration period T is not connected with quality of pendulum ball; to study simple pendulum vibration period is inversely proportional to square root of acceleration of gravity and to determine acceleration of gravity value. It is used for physics teaching demonstration and student experiment in group at middle schools, colleges & universities and vocational schools.
