 Another type of analog computers include mechanical ones.
During WW2, they used really complicated mechanical fire
control computer. One would input range, bearing, projectile
and charge. It would also take into account ship roll, speed
and coriolis effect for that target.
 Gear ratios would make coefficient multipliers. They had variable
speed transmissions to make multipliers. Differentials made adders
and subtracters.
