APPLICATION

Rectangular form hull with distributed loading.
Maximum number of loads 200.

OUTPUT

Tabulated shear force & bending moment distributions.

THEORY

hydrostatics and statically determinate beam theory

GUIDANCE

X1 Distributed load P is idealised as linearly varying from p1 to p2 between X1 & X2.
1st loading band in the input table is the hydrostatic reaction.
Mmax and the corresponding xmax within each continuous loading band are reported in the output. Mmax=0 & xmax=0 are reported if no minima or maxima is found.
