The dual diameter wheel has an axle supported on simple pivots in a sturdy wall mounting bracket. Each wheel has a cord wrapped around its periphery. The cords can be wrapped in either direction around each wheel. A load hanger is added to each cord allowing loading of the wheels using the calibrated weights set provided.
Using the hangers and weights allows the experimental determination of velocity ratio and comparison with calculated values. Students can also determine the variation of effort with load and the variation of efficiency with load.
A comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results. All necessary assembly and operational tools are provided.
Optional accessories: HAC14
