Shoulder Pull Formula Derivation
Shoulder Pull is the centripetal force, in Newtons,with the shoulder being a distance R (= 0.61 + r/100) meters from the racquet mass center. The Shoulder Pull force, measured in units of Newtons (1 Newton = 0.225 lb.) attributable to the racquet alone is derived from the Work formula and the general formula for centripetal force (centrifugal force). See the accompanying remarks. A complete description of all variables used in this derivation follows at the end.
