Fabric cords A and B have the same specific gravity and are both
made of two twisted yarns. Cord A has a denier of 1,079 and is
twisted at 9 twists per inch. Cord B has a denier of 894. How many
twists per inch (TPI) must cord B be twisted to in order to have
the same helical angle and thus same fatigue and tenacity
properties?
