Just choose your segment lengths so that the center of a segment is
(in your example) at 7.68 cm, and put the load in that segment.

Read the instructions for the LD command. You can specify
"distributed" loading, with specified wire conductivity, e.g. 5.7E7
S/m.

NEC normally prints the complex current in each segment.
