What is the relationship between friction and stress in the climber?

The coefficient of friction between the wheels and ribbon determines the stress state in the whole drive mechanism

Lower coefficient of friction harder the climber has to pinch the ribbon

The wheels and axles are in fully reversed contact or bending stress

Fatigue failure is the result of cyclic stress

Fully reversed bending causes the worst material damage
