Summary[edit]

Description
English: Diagram showing straight-line paths for angles of entry into "pocket" (assumes ball is centered at board 17.5 at impact), specifically for angles of entry of 2, 4, and 6 degrees.

Round-off error in representations may result from Microsoft Powerpoint's accepting only two significant digits to right of decimal point.

Calculations assume center of bowling ball is centered on board 17.5, and 6.38 inches up-lane from center of head pin. Board 20 is centered 41.5/2=20.75 inches from edge, minus 2.5 inches from board 20 to board 17.5 = 18.25 inches. Board 17.5 is 18.25 inches from right edge of lane.

  • 18.25 / tan 2° / 12 = 43.57 feet up-lane from center of ball at impact
  • 18.25 / tan 4° / 12 = 21.75 feet up-lane from center of ball at impact
  • 18.25 / tan 6° / 12 = 14.47 feet up-lane from center of ball at impact
