Cable Element External Forces External Forces: FI = Inertial Force
FN = Normal Fluid Force
FT = Tangential Fluid Force
FB = Buoyant Force
V = Speed of element wrt fluid
dV/dT = Acceleration of Element wrt.
Fluid SG = Cable Specific Gravity
rho_fluid = Working fluid Density
theta = Angle between segment Tangent and segment velocity Forces on Element:
FT = - 1/2 fluid V |V| CT
FN = - 1/2 ? fluid V |V| CN
FI = - dV/dt Mass
FB = -Axs s g ? fluid (SG- 1)
