DESCRIPTION
Exploring Structural Engineering Fundamentals. Strength of Shapes. Shapes in Bridges. Shapes in Buildings. Shapes in Other Things!. Relative Strength of Shapes. On your paper, sketch what you think will happen to these shapes if we apply the force shown in GREEN (assume the sides are rigid). - PowerPoint PPT PresentationTRANSCRIPT

Relative Strength of Shapes On your paper, sketch what you
think will happen to these shapes if we apply the force shown in GREEN (assume the sides are rigid)

Relative Strength of Shapes The TRIANGLE is the only shape that
won’t collapse! WHY?
![Page 7: Strength of Shapes](https://reader036.vdocuments.site/reader036/viewer/2022062501/5681638c550346895dd47c60/html5/thumbnails/7.jpg)
The other shapes collapse because the angles between the structural members change.

Triangles The TRIANGLE cannot collapse
because the angles are fixed based on the opposite side length.

All other shapes can be deformed because the angles are not fixed. Draw these shapes in a way that will keep them from collapsing.
