Axial forces on crutches

[Antonio Asugusto Fasolo Quevedo]

I'd like to thank to all those people who helped me when I needed
information about axial forces on crutches. My special thanks go to :
-Paul Guy, who gave me important information about load cells;
-Ricardo Torres-Moreno, who told me about the papers in this area;
-Bruce Knoth, who offered to give information about multi-axis
load cells;
-Moti Zimmerman, who sent me a paper about the subject;
-Mike Dolan, who gave me more information about papers and people
who work with this;
-Jerome A. Gilbert, who gave me still more information about papers

Thank you very much !
