1. A drilling system, comprising:
an internal assembly comprising:
a chassis enclosing an instrumentation tool of the drilling system;
an electronics board of the instrumentation tool located within the chassis; and
a strain gauge coupled to the electronics board, the strain gauge being configured to output a signal associated with a strain deformation of the internal assembly, wherein the strain gauge includes a torsion strain gauge measuring torsion strain deformation of the electronics board, and isolated from in-plane bending, out-of-plane bending, and axial strain deformation of the electronics board; and
a drill collar coupled to and enclosing the internal assembly such that a strain deformation of the drill collar causes the strain deformation of the internal assembly.
