Inertia and surface

Computes the inertia of bending and torsion, and the cross-section area

InertieFlexRota(b, h, agDeg, sct, N = 100)

Arguments

b

Dimesion of the base
h

Dimension of the height
agDeg

section orientation angle (torsion, in degrees)
sct

Section type (see details)
N

Number of discretizations (default to 100)

Value

A list of three:

  • IgFlex : bending inertia

  • IgTor : torsion inertia

  • Sr : cross-section surface

Details

For the section type, possible values are:

  • sct = 1 : triangle (bottom-oriented)

  • sct = 2 : rectangle

  • sct = 3 : triangle (top-oriented)

  • sct = 4 : ellipsis

  • sct = 5 : circle
