ABSTRACT:
A device for measuring the coefficient of friction between a test surface and a test material, comprising a frame, a skid pad comprising the test material and attached to an underside of the frame to contact the test surface, a longitudinal force measuring device attached to the frame and having an axis, and a longitudinal pulling assembly exerting a longitudinal pulling force on the drag sled and the longitudinal force measuring device. The longitudinal force measuring device is capable of outputting data indicative of the longitudinal force applied to the device. The longitudinal pulling force is vertically aligned with the axis of the longitudinal force measuring device.
