Approximation -> Let's say that a point "P" in the middle of the the shoulders are the center of all rotation. Use "RPM" as the basic RPM of the pivot. Left shoulder (surface) speed = (2 * radius1 * pi * RPM)*60, radius1 = P->left shoulder, unit = m/s. Hand (surface) speed = (2 * radius2 * pi * RPM)*60 + hand overtaking speed, radius2 = P->hands, unit = m/s. Clubhead (surface) speed = (2 * radius3 * pi * RPM)*60 + hand overtaking speed + clubhead overtaking speed, radius3 = P->clubhead, unit = m/s. Note: radius1 is constant, radius2 increases sligthly in downswing, radius3 increases more. Another way to see it(but less usefull) would be that left shoulder, hands and clubhead have different RPMs. PBH View Public Profile Send a private message to PBH Find all posts by PBH Page 10 of 10 « First < 89 10 « Previous Thread | Next Thread » Thread Tools Show Printable Version Email this Page Display Modes Linear Mode Switch to Hybrid Mode Switch to Threaded Mode Posting Rules You may not post new threads You may not post replies You may not post attachments You may not edit your posts vB code is On Smilies are On [IMG] code is On HTML code is Off Forum Jump User Control Panel Private Messages Subscriptions Who's Online Search Forums Forums Home The Club Office Forum Information – News and Posting Rules Media Center Announcements Forum and Web Site Suggestions The 19th Hole Yoda's Corner LBG Testimonials On TOUR With LBG LBG Gallery of Champions The Golf Channel Instructor Search John Riegger's TOUR Talk The Caddy Shack The Clubhouse Lounge Hole-ies and Pole-ies Dusted & Fried--Down Home with 12 piece bucket Scheduled Schools, Master Classes and Special Events Past Schools and Master Classes LBG Academy at Orange County National / Orlando / November 11-13, 2005 Destin - Bash at the Beach The Links at Shirley Three Golf Guy's and You - Woodmont CC Pine Needles Orange County National Rob Noel Academy - Masters Class Yoda and Henning at 2006 PGA of Sweden Teaching Summit LBG Academy at Old Waverly / April 21-23, 2006 The Advanced Junior Golf Academy At Money Hill / May 20-21, 2006 Barclays Classic Golf Academy / June 5-11, 2006 LBG Academy at Hude, Germany / August 5-8, 2006 The Academy At Money Hill / October 13-15, 2006 LBG Instructors Academy At Hombre Golf Club / December 11-13, 2006 Verizon Communications Executive Clinic / November 14, 2006 / Windermere, Florida LBG Academy at Falcon's Fire Golf Club / Kissimmee, FL / March 16 - 18, 2007 LBG Academy at Las Vegas Paiute Golf Resort / Las Vegas, Nevada / May 4-6 , 2007 The Barclays Golf Academy Presented By Lynn Blake Golf The Golf Academy Presented By Gillette Fusion Power The Golf Academy at Hyatt Hills (NJ) / August 17 or 18, 2007 LBG Homecoming Classic At Cuscowilla Golf Club and Resort / October 9-12 , 2007 The Barclays Golf Academy Presented By Lynn Blake Golf / 2008 The Barclays Golf Academy 2009 / Presented By Lynn Blake Golf, LLC Carolinas Section PGA Workshop / Alignment Golf / March 15-16, 2010 / Greensboro, NC Alignment Golf Workshop / Greensboro, NC / March 9-10, 2011 Pinetree CC / December 8-9, 2010 Carolinas Section PGA Workshop / Alignment Golf / December 12-13, 2011 / The Club at Irish Creek, Ch Two Day Corporate Outing / Cuscowilla Ocean Reef Workshop / Key Largo, FL / April 4-5, 2012 Lynn Blake Golf Academy at PGA Of Southern California Golf Club / October 28-30, 2005 2013 Majors The Masters 2013 Past Majors The United States Open 2006 The Masters 2006 The Open Championship / July 20-23, 2006 The PGA Championship / August 14-20, 2006 The Masters - 2007 U.S. Open - 2007 The Masters 2008 U.
