    derived - meaning

    Hello everybody!

    I would like to ask you about the meaning of the verb "derive" in the past participle form in the sentence below.

    The group classification of the crane into classes A1 to A8 is derived as a combination of the two duty factors U and Q.

    What do you think it means?

    It does not tell me anything.

    We are talking about cranes again.

    Here is some more context:

    DWP calculation for cranes designed to ISO 4301-1

    A.l General

    Two basic duty factors and the crane classification as a combination of the two duty factors are presented in ISO 4301-1:

    the number of work cycles, grouped into classes Uo to U9;

    a load spectrum factor, Kp, grouped into classes Q1 to Q4.

    Re: derived - meaning

    The group classification comes from a combination of U & Q. (I think)
