| RATIO OF THE MOMENT OF INERTIA OF E.A.C & GOSHAWK CLUTCH PLATES. E.A.C. CLUTCH PLATE. SECTION. Diagram Dimensions (from top to bottom, left to right): .10, .07, .06, .09 2.5 RAD, 4.2 RAD, 7.0 RAD AXIS OF ROTATION. GOSHAWK CLUTCH PLATE. SECTION. Diagram Dimensions (from top to bottom, left to right): .10, .06, .10 2.45 RAD, 4.0 RAD, 5.2 RAD AXIS OF ROTATION. I EAC / I GOSHAWK = 5.6 OR - MOMENT OF INERTIA OF E.A.C. CLUTCH PLATE IS 5.6 TIMES THAT OF GOSHAWK | ||
