How to determine the dimensions of conveyor and power ...

Because the correlation of force and elongation of synthetic material is influenced by time (Relaxation), it is important to know the k1% value after the relaxation. Both k1% static and relaxed are valid measures for conveyor belts and machine tapes. Power transmission with flat belts is a highly dynamical process.
