13. A drilling assembly, comprising:
a first rotary tool comprising a first contacting structure configured for contacting a formation;
a second rotary tool rotatable with the first rotary tool and comprising a second contacting structure configured for contacting the formation at a position axially spaced from the first contacting structure;
at least two force sensors positioned to obtain a force applied above the second contacting structure and a force applied below the second contacting structure, each force sensor comprising a strain sensor incorporated into a respective strain puck, each strain puck removably received within a respective recessed area of a drilling assembly component; and
a controller in electronic communication with the force sensors configured to obtain a force differential between the force applied above the second contacting structure and the force applied below the second contacting structure, and wherein the controller determines whether each strain sensor is calibrated in a proper alignment with compression and/or torsional forces applied to the strain gauges based on a response from the strain pucks to the compression and/or torsional forces.
