1. A tribometer for determining frictional torque at an interfacing of two components, the tool comprising:
a first platform to accommodate a first of the two components;
a second platform to accommodate a second of the two components in alignment with the first component, the platforms to facilitate the interfacing of the components;
a first motor to rotate the first component about a shared axis;
a second motor to rotate the second component about the shared axis; and
at least one torque meter to measure frictional torque of the rotating components.
