1. A drilling system, comprising:
an internal assembly comprising:
a chassis enclosing an instrumentation device of the drilling system; and
a strain gauge coupled to the chassis, the strain gauge being configured to output a signal associated with a strain deformation of the internal assembly:
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; and
a drill bit coupled to the drill collar, the chassis including a flow diverter configured to direct fluid moving through the drilling system and toward the drill bit, away from the instrumentation device.
