Center Of Gravity Apparatus

A Simple And Economical Apparatus For Demonstration Of Geometrical Center Of Gravity Of Two-Dimensiol Objects. Center Of Gravity Of A Freely Suspended Two Dimensiol Object Always Lies Along The Line Drawn Vertically Downward From Its Point Of Suspension. Comprises A Clear Perspex Rod Mounted On A Base With A Suspension Screw At The Top And Four Lamis Of Clear Acrylic, One Each Of Circular, Triangular, Square And Trapezoidal Shape. Each Lami Has Suspension Holes Along Their Periphery. The Point Of Intersection Of Lines Drawn From Point Of Suspension Of 2 Or More Holes Of A Lami Gives Center Of Gravity Of That 2-Dimensiol Lami.
