Примерно так же, как и на прочих комбинированных судах (был такой шведский монитор береговой обороны - с дизель-электрическим экономходом и форсажными турбинами) - электромотор находится на том же валу и работает совместно, диапазон оборотов вполне это позволяет.

Кстати замечу - веса можно считать по-размомну, относя к той или ионой статье. Те же "Светланы" или оба "новика  в Шарпе дают другие цифры, при общем нормальнм результате. ВОт, например, первый "новик" - с той же самой, что характерно, прочностью корпуса получился:

Безусловно верить стоит, поскольку Вика здесь цитирует Цветкова:

К сожалению, в сети пока не нашел ту схему бронирования "Светлан" из старого "Судостроения"...
Если "моя память не спит с другим"(с), верхний пояс там сам выступает в роли внешней обшивки.
А вот главный пояс уже навешивается на обшивку...
Примерно как вот приведено у Виноградова в "Последних исполинах российского императорского флота":

Принцип один и тот же: "тонкая" вертикальная броня сама (без каких либо подкладок) выполняет функцию внешней обшивки от верхней палубы до нижней кромки скоса бронепалубы.
На уровне от нижней кромки скоса бронепалубы до средней палубы на неё навежен "главный" БП.

Нашел упоминания этого (и прям - под копирку):

- и пребываю в озадаченности...
Увы - хорошего мидель-шпангоута ни по Магдебургам/Грауденцам, ни по послевоенному Эмдену найти не удалось.
Но вот весовую сводку Магдебурга в "Марине-Рундшау" за 1981 год нашли:
1.корпус -35,7%
2.броня - 13,4%
3.Главная энергетическая установка -25.1%
4.Вспомогательные машины 2,3%
5.Артиллерия с боеприпасами 3,9%
6.Торпедное вооружение 1,2%
7.??? Оборудование, судовые запасы включая воду 7,4%
8. Нормальный запас топлива 9,9%
9. Прочее и резерв 1,1%

И она с Вашей развесовкой никак не бьётся...
