아우름 볼링 클럽

RPM은 Revolutions Per Minute 의 약어로 분당 회전수를 말며 Rev Rate라도고 합니다. (이하 Rev Rate라고 하겠습니다.) Rev Rate를 구하는 식은 (회전수 × 60)÷시간.  60은 1분 결국 회전수와 자신의 시간을 알아야 합니다. 파울라인에서 1번 핀까지 도달하는 시간은 스톱워치로 쉽게 알 수 있지만 회전수는 정밀한 영상도구없이는 그 측정이 쉽지 않습니다. 가장 이상적인 볼 도달시간은 2.4초이며 이와 동시에 16회전이 이루어 졌을 때라고 합니다. 이를 대입하여 Rev Rate를 계산하면 Rev Rate = (16 × 60) ÷ 2.4                 960 ÷ 2.4 = 400               ∴ Rev Rate = 400 이라는 계산 결과를 얻을 수 있습니다. 이때 속도는 MPH로 측정된 숫자이며 1마일을 나타냅니다. 미국 야구 경기를 시청하신 분께서는 공 스피드가 마일로 측정되어 표기 되는 장면을 보았을 것입니다.   이번 2008~2009 Season에는 유독 선수들의 볼 스피드와 RPM이 자주 나왔습니다. 볼 스피드는 스피드 건을 이용하여 쉽게 측정이 됐는데 각 선수들의 도달 시간은 화면에 표시 되지 않았습니다. 속도만으로 Rev Rate를 구할 수 는 없으며 도달 시간이 나와야 쉽게 답을 얻을 수 있습니다. 다음은 스피드와 그에 상응하는 시간을 기록한 표입니다. <TABLE style="WIDTH: 538pt; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=0 width=716 border=0 x:str=""> <COLGROUP> <COL style="WIDTH: 122pt" width=163> <COL style="WIDTH: 49pt" span=3 width=65> <COL style="WIDTH: 122pt" width=163> <COL style="WIDTH: 49pt" span=3 width=65></COLGROUP> <TBODY> <TR style="HEIGHT: 18.75pt" height=25> <TD class=xl22 style="BORDER-RIGHT: rgb(224,223,227); BORDER-TOP: windowtext 1pt solid; BORDER-LEFT: windowtext 1pt solid; WIDTH: 122pt; BORDER-BOTTOM: black 1pt solid; HEIGHT: 337.5pt; BACKGROUND-COLOR: silver" width=163 height=450 rowSpan=18> 가정 1.  가. 파울라인에서 1번 핀까지의 거리 60Ft 나. 레이다운 포인트는 파울 라인 참고1.( Lay Down Point란 릴리스 된 후에 볼링 첫 번째로 Lane에 닿는 지점을 말합니다.) 참고2.(MPH는 마일, KPH는 킬로미터)                   </TD> <TD class=xl37 style="BORDER-RIGHT: black 0.5pt solid; BORDER-TOP: windowtext 1pt solid; BORDER-LEFT: windowtext 1pt solid; WIDTH: 49pt; BORDER-BOTTOM: windowtext 2pt double; BACKGROUND-COLOR: silver" width=65> 시간</TD> <TD class=xl38 style="BORDER-RIGHT: black 0.5pt solid; BORDER-TOP: windowtext 1pt solid; BORDER-LEFT: black; WIDTH: 49pt; BORDER-BOTTOM: windowtext 2pt double; BACKGROUND-COLOR: silver" width=65 x:str="MPH "> MPH </TD> <TD class=xl39 style="BORDER-RIGHT: windowtext 1pt solid; BORDER-TOP: windowtext 1pt solid; BORDER-LEFT: black; WIDTH: 49pt; BORDER-BOTTOM: windowtext 2pt double; BACKGROUND-COLOR: silver" width=65 x:str="KPH "> KPH </TD> <TD class=xl25 style="BORDER-RIGHT: rgb(224,223,227); BORDER-TOP: windowtext 1pt solid; BORDER-LEFT: rgb(224,223,227); WIDTH: 122pt; BORDER-BOTTOM: black 1pt solid; BACKGROUND-COLOR: silver" width=163 rowSpan=18> 가정 2.   가. 파울라인에서 1번핀까지의 거리 60Ft   나.

Rev Rate가 259이며 스피드가 18.7MPH입니다. 회전수 : ( y × 60 ) ÷ 2.18 = 259            y × 60 = 2.18 × 259            y × 60 = 564.6            y = 564.6 ÷ 60           ∴ y = 9.41입니다. 이를 토대로 두 선수의 정보를 보면 <TABLE style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px; LINE-HEIGHT: 150%; BORDER-COLLAPSE: collapse" cellSpacing=0 width=639> <TBODY> <TR> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=88 bgColor=fuchsia>  </TD> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=133 bgColor=fuchsia> 회전수</TD> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=124 bgColor=fuchsia> 스피드</TD> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=154 bgColor=fuchsia> 도달시간</TD> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=106 bgColor=fuchsia> Rev Rate</TD></TR> <TR> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=88 bgColor=#99ff66> Chris Barnes</TD> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=133 bgColor=#99ff66> 13.9회전</TD> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=124 bgColor=#99ff66> 20.1MPH</TD> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=154 bgColor=#99ff66> 2.03초</TD> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=106 bgColor=#99ff66> RPM 410</TD></TR> <TR> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=88 bgColor=#0066ff height=11> Norm Duke</TD> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=133 bgColor=#0066ff height=23> 9.4회전</TD> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=124 bgColor=#0066ff height=23> 18.7MPH</TD> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=154 bgColor=#0066ff height=23> 2.18초</TD> <TD style="BORDER-RIGHT: black 1px solid; BORDER-TOP: black 1px solid; BORDER-LEFT: black 1px solid; BORDER-BOTTOM: black 1px solid" width=106 bgColor=#0066ff height=23> RPM 259</TD></TR></TBODY></TABLE>   위와 같은 방법은 통해서 여러분의 정확하지는 않지만 약간의 Rev Rate를 구할 수 있습니다. 정확한 답을 얻고 싶으시면 회전수를 측정할 수 있는 영상기기와 프로그램이 있어야 합니다.
