In pre-stressing work, if more than one wire or strand is included in the same duct, why should all wires/strands be stressed at the same time?

Question

If wires/strands are stressed individually inside the same duct, then those stressed strand/wires will bear against those unstressed ones and trap them.

Therefore, the friction of the trapped wires is high and is undesirable.
