摘要
[編輯]描述20181230 Bowling ball at board 17.5 with pins.png |
English: A ten-pin bowling rack with a bowling ball impacting the head pin while the ball is centered on "board 17.5", which is believed to be the impact point providing the greatest likelihood of striking. Diagram demonstrates that, contrary to common belief, the ideal "pocket" is not "between" the 1 and 3 pins.
Changes arriving at the third, fourth, etc. versions are relatively minute.Diagram also demonstrates how pins other than pins 1 and 5 are not set on boards that are multiples of 5. Beginning with Version 3, diagram also shows entry angles of 0°, 2°, 4° and 6°.

This FOURTH version is believed to be the most accurate. Incidental changes: removed fringe from layers of bowling ball, and added subtle shadows to give dimensionality. | ||

2018年12月31日 (一) 01:18 | 2,366 × 2,953(552 KB) | RCraig09(留言 | 貢獻) | Bowling ball is shifted from being centered from middle of Board 17, to the boundary between Boards 17 and 18 -- a half-inch move. There is ambiguity as to what "Board 17.5" means, so I'm uploading versions for each interpretation. | ||
