where
A4 - bending moment
T - torque
ap - axial stress due to static or pulsating loads
tp
- shear stress due to static or pulsating loads
I - moment of inertia
J - polar moment of inertia
£ - distance from the zero-stress point to the
point of interest.
The scale ratios for bending moment and torque are found by taking the
prototype-to-model ratios for moment and torque, recognizing that Nj —
Nj =
and substituting the Froude scales NOp = NTp = NgNi to get
= Ng (NL)4
and
Nt = Ng (7VL)4
