How do you measure rolling torque?

Rolling torque can be measured using a torque sensor or transducer that is placed in the drivetrain of a vehicle or machinery. The sensor detects the torque generated during rolling motion, typically by measuring the force applied to the wheel or axle. Data is collected during operation, often under various loading conditions, to assess the torque performance. This information can then be analyzed to understand the efficiency and behavior of the rolling system.
