People need to realise that at DIY level the calculations mostly don't apply. Yes can't get away from pyhsics etc but most calculations are based on ridgid values and strict rules. They don't account for the DIY affects of muppets like US in working in sheds.

My thoughts on Calculations are don't waste the time,!! Instead invest the time looking for Real world examples and ask the person who made it what would do better.
The best Machines I've seen built have been built using just 3 Goods.?? . . . . . . . Good research, Good attention to detail and Good Old Common Sense.
