They make street art. A Mohr’s Circle is a two-dimensional representation of stresses in materials. Compare the representation of stresses above with the more technical one below.
Nice. Here’s Wikipedia’s explanation of just why one might do this:
Internal forces are produced between the particles of a deformable object, assumed as a continuum, as a reaction to applied external forces, i.e., either surface forces or body forces. This reaction follows from Euler’s laws of motion for a continuum, which are equivalent to Newton’s laws of motion for a particle. A measure of the intensity of these internal forces is called stress. Because the object is assumed as a continuum, these internal forces are distributed continuously within the volume of the object.
So, here’s the Icelandic version again:
Lots of permutations through stress there, all delightfully witty.
I think that’s it.
Never say there isn’t humour, art and beauty in Iceland.
