Dynamic to be connected with tensiometer, the upper end of the tensiometer is connected by the top of spring and groove, and the lower end of the tensiometer passes through
Wirerope-winding is in line wheel.
It is preferred that the both sides of the groove are provided with friction plate.
It is set it is preferred that be fixedly connected with slide bar on the rotor plate, on the slide bar there are two pulley, on the pulley
Balance weight is connected with by drawstring.
It is preferred that it is provided with storage box on the pedestal.
It is preferred that the bottom surface of the pedestal is provided with universal wheel.
The beneficial effects of the invention are as follows：
The multi-functional mechanics apparatus for demonstrating of Physical Experiment provided by the invention is turned by the 3rd the second turntable of driven by rotary disc
Dynamic, the second turntable drives the first turntable to rotate again, and when the first turntable rotates clockwise, the steel wire rope in line wheel is shunk, so as to
Rotor plate is driven to be raised above, thus by tensiometer it is seen that with the rotation of the first turntable, the variation of pulling force；When
When one turntable rotates counterclockwise, the steel wire rope pulling in line wheel, so that rotor plate falls downward, effectively changes rotatory force
Pulling force understands convenient for student, mitigates the working strength of teacher, improves mechanics teaching efficiency.
