Diameters and dome strengthFeatured science projectScience project video


The results show that increasing the diameter of the dome (or the dimension D of the arch) while maintaining its height will make the construction weaker, due to vertical stress.

Measurement Support strength of dome for increasing dome diameter
Dome diameter D (mm) 511 609 707 803 901
Collapse weight (kg) 8.6 8 7.1 5.9 4.3

The above results were then plotted onto a graph, as shown below.
