The M-15 Mechanicals

1. With a large 8,500mm (circumference) road wheel, the contact patch is flat to 0.5mm, (but obviously dependent on tire diameter and pressure).
2. Load is electronically generated up to 22.3kN (or 5,000lb).
3. Slip angle is up to +/-15 degrees and digitally measured with an absolute encoder to 0.0176 degree resolution (absolute encoders exhibit zero drift even when powered down).
4. Zero degrees is mechanically locked to an accuracy of 0.0005 degree accuracy.
5. Speed is controlled at 10kph to +/-0.1kph and stable from 3.5 kph up to 100 kph.
