Abstract
A drilling system may include one or more downhole components to which a torque is applied. To determine the torque, the rotational velocity may be determined at two locations on a downhole component. An angle of twist may be determined by taking the integral of the rotational velocity at the two points, and the torque may be proportional to the angle of twist. The angle of twist, physical properties based on the geometry and material of the downhole component may be used, and the distance between the two locations may be used to calculate the torque.
