Technical diagram charting the precise trajectory of a billiard ball shot from an aerial perspective 插畫檔

This clean, technical engraving provides a top-down geometric overview of a billiard table, illustrating the physics and strategic trajectory of a trick shot. The rectangular table is enclosed by a heavy wooden frame with a distinct grain pattern, marked with letters A, B, C, and D on each of its sides to serve as coordinates. On the left side, a billiard cue tip is positioned just behind a white cue ball, with a straight line stretching horizontally across the felt to show the path of the shot toward two balls nestled closely together near the right cushion. Upon impact, the line splits into an elegant, curved loop that demonstrates the complex physics of ball spin and deflection, complete with a dotted circular outline near the bottom corner cushion indicating a potential target area or pocket entry vector. Published as part of an instructional sports manual or scientific treatise on mechanics in the nineteenth century, this clear analytical illustration traces its origin back to France.
