togo: The formula you listed for J1 and J2 in post 10 is currently wrong, and does not match the right-hand side. Also, review the information in post 3.
(1) The unit symbol for newton is uppercase N, not lowercase n. Lowercase n means nano.
(2) Numbers less than 1 must always have a zero before the decimal point. E.g., 0.04, not .04. See the international standard (ISO 31-0). Or see any credible text book.
