He correctly assumed a central neutral axis and linear stress distribution from tensile at the top face to equal and opposite compression at the bottom, thus deriving a correct elastic section modulus of the cross sectional area times the section depth divided by six.

The " neutral line " ( also called the " neutral axis " ) is an imaginary line that can be drawn through the cross-section of the workpiece that represents the locus where no tensile nor compressive stresses are present on the work.

I know that I have to use the ratio of the Young's Moduli to scale the widths to find the neutral axis, but must I also scale the widths when calculating the moment of inertia ?-- Joe 16 : 44, 19 May 2007 ( UTC)

This organism undulates as a homogenous beam ( just as in fishes ) during swimming; thus the distance of a muscle fiber from the neutral axis ( z ) during bending must be greater for external oblique muscle layers ( EO ) than internal oblique muscle layers ( IO ).
35.
A bow limb is essentially a flexed beam undergoing bending, and in any flexed beam the farther from the neutral axis ( line in the middle of the flexing beam which is not under tension or compression : see diagram in Bending article ) the more stress there is within the material.

HSL and HSV are simple transformations of RGB which preserve symmetries in the RGB cube unrelated to human perception, such that its " R ", " G ", and " B " corners are equidistant from the neutral axis, and equally spaced around it.
37.
In the case of T-sections if there are tensile fibres at the bottom of the T they may still be more critical than the compressive fibres at the top due to a generally much larger distance from the neutral axis so despite having a higher allowable the elastic section modulus is also lower.

Alt = When an RGB cube, tilted so that its white corner rests vertically above its black corner, is projected into the plane perpendicular to that neutral axis, it makes the shape of a hexagon, with red, yellow, green, cyan, blue, and magenta arranged counterclockwise at its corners.

In a flatbow, the flat belly and back ensure that all of the most strained material is a uniform distance from the neutral axis, spreading the load over a wider limb, minimizing stress and making weaker woods far less likely to fail ( break or become permanently bent and lose the resilience needed in a bow ).

The relationship between the strains ( ? ) experienced by the EO and IO and their respective z values is given by the following equation : where ?EO and ?IO = strain of the external and internal oblique muscle layers, and zEO and zIO = distance of the external and internal oblique muscle layers respectively from the neutral axis.
