Force edit

The internal forces in the certain member point can be entered with the help of this window. These properties can be specified:

x

  • Basic input, that specifies the position of the point along the member length. The position is measured from the left end of the member

N

  • Normal force

M2

  • Bending moment about axis 2 (positive values represent tension in the bottom edge of the cross-section)

M3

  • Bending moment about axis 3 (positive values represent tension in the left edge of the cross-section) - only selected programs and task types

V3

  • Shear force in vertical direction (parallel with axis 3)

V2

  • Shear force in horizontal direction (parallel with axis 2)

Tt

  • Torsional moment about member axis 1 - St. Venant torsion

Tω

  • Torsional moment about member axis 1 - Warping torsion

B

  • Bimoment

Values of all internal forces shall be specified only in the first (x=0) and last (x is equal to member length) sections. Intermediate sections may contain unfilled certain internal forces. The values of these forces are obtained with the help of linear interpolation using the closest values that were specified in other sections.
