A Fast Offshore Cruiser - Appendices.
A.7. - Rudder stock.
(cm) = solid stock diameter
s c = the lesser of or minimum yield strength N/mm2 (for metals)
s c = 215 N/mm2 = 21500 N/cm2 for Stainless Steel 316
(Ncm) = Torque @ neck (lower) bearing
(Ncm) = Moment @ neck (lower) bearing
(N) = total force on rudder
k = 984, C = 1.5, LWL = 14.66m, A = 0.856m2
\ N = 1.0
hb = 192.36cm, h = 177.56cm, hc = 76.61cm
at top bearing M = 0
at the stock tip (0.2 * rudder depth from blade tip) dmin = 0.46*d at neck bearing = 4.44cm
