Uses in to explain the plate-type object the center of gravity asksthe law
Structure:
The instrument by the experimental board, the suspension hook, theprop (attaches thimble), the foundation composes The experimentalboard has the circular, the square, the rectangle, the triangle, thetrapezoid, the polygon board each together In the board corner openshas the eyelet, the board center of gravity is loaded with the bearing
Usage:
Passed through the eyelet with the suspension hook to hang theexperimental board is hanging, attaches in the suspension hook lowerextremity 重垂线, took down by now on the experimental board重垂线 Again takes on the experimental board in another cornereyelet, the repetition above procedure Takes down once more thestraight line point of intersection, then is this experimental boardcenter of gravity Is supporting the experimental board center ofgravity with the thimb
