Sigh.
I spoke too soon. Not so simple after all.
I can get away with dazzling the three-year-old with the engine torque theory, but I fear this is still going to bug me, thanks to Wiley and Speedpig
(thanks all the same).
Anyone written a definitive work on early carrier design?
If so you probably need to get out more, but I'd love to hear from you if can answer this.
