TM1002 Static-Dynamic Balance Experiment Device
This is a tabletop device for experimenting with static and dynamic balance in rotating bodies. Four balance blocks are set on a steel shaft held by bearings, and an electric motor and belt rotate the shaft. The four balance blocks have the same mass, but by changing the position and angle of the removable circular inserts at the tips, different masses and moments of the blocks can be created. The set shaft moment can be accurately measured using the included pulley and weights. It is confirmed to be in static balance at any angular position, and the dynamic balance imbalance is checked by rotating the shaft and observing the vibrations from the four rubber mounts. The transparent protective cover is equipped with an interlock mechanism that stops the rotation when the cover is opened.
