Simple Bending Equation: Difference between revisions

Latest revision as of 20:03, 3 September 2016

The Simple Bending Equation applies to simply supported beams (and arches if the radius of curvature is greater than 10 times the depth)

Where:

M = the Maximum Bending Moment
σ = the Tensile Strength of the material (obtainable from tables or by experiment)
Capital I = the Moment of Inertia about the Neutral Axis (for a rectangular beam this is its breadth times the depth cubed divided by 12).
y = the distance of the Neutral Axis from the maximum stress (for a uniform rectangular beam this is half the depth)

Simple Frames and Linkages can be explored using Construction Kits such as those listed below.

More varied models can be constructed using the materials listed at Truss Bridge Models or Stripwood Technology Materials and tools described in Stripwood Technology Tools.
