What happens to torque readings when the distance from the center of rotation is altered in a torque transducer calibration?

When the distance from the center of rotation is altered in a torque transducer calibration, the torque readings become inaccurate. This is because torque is directly related to both the force applied and the distance from the pivot point (or center of rotation) at which that force is exerted. The torque is calculated using the formula ( \text{Torque} = \text{Force} \times \text{Distance} ).

If the distance changes, while the force remains constant, the resulting torque measurement will also change. This discrepancy leads to inaccurate readings since the calibration is based on precise measurements at a specific distance. Accurate torque calibration relies on maintaining a consistent distance to ensure that the calculated torque value reflects the true performance of the system being tested. Hence, any variation in this distance directly impacts the accuracy of the readings obtained from the transducer.
