| I. ANGULAR RATE T' = dT/dθ = Wr II. ANGULAR RATE T' = Wb {Mr Brazier / Mr Bell} b = da {Bernard Day - Chassis Design} /dθ ; -a = db {Donald Bastow - Suspensions} /dθ III. SPRING RATE S T = Pb T' = d {John DeLooze - Company Secretary} /dθ (Pb) = dP/dθ x b + db {Donald Bastow - Suspensions} /dθ x P = dP/da {Bernard Day - Chassis Design} x da {Bernard Day - Chassis Design} /dθ x b - Pa {Mr Paterson} = Sb {Mr Bull/Mr Bannister} ^2 - Pa. {Mr Paterson} IV. S = rate T' = Sb {Mr Bull/Mr Bannister} ^2 - Pa {Mr Paterson} x (l+a)/l by May 16/40. | ||
