In this paper we attempt to find the effect of the rolling of ships on the transverse strength and deformation of ships by the aid of relaxation method. To lighten the labour of calculation, we assume the ship is at the maximum inclination : that is
dθ/dt=0
Then the centrifugal forces vanish and only the inertia forces remain. Calculation is done at 10°, 20° and about 27° inclination : the last one is the angle at which the edge of the bridge deck immerges. On this calculation, we conclude that both statical inclination and inertia forces are not serious on the transverse strength.
The centrifugal forces are conjectured so.
Then as regards to the moment distribution or stresses we do not need the calculation of inclined condition : the one when the ship is upright is sufficient. But as regards to the deformation statical inclination exercises so great influences that we suppose this as one of the serious factors of racking.
