2.1. Reference quantities and results#
The reference quantity used are the displacements along \(X\) and \(Y\) of the point \(C\).
Analytical solution:
Rotation of \(90°\) around the point \(D\): \(C(\mathrm{1,1})\to C(\mathrm{0,2})\)
Translation of (-1.1): \(C(\mathrm{0,2})\to C(-\mathrm{1,3})\)
The reference movements are deduced from this at point \(C\):
\(\mathrm{DX}=-2m\)
\(\mathrm{DY}=2m\)
