Dear friends,
When a body (shafts included) moves through a fluid it is always better to have the centre of gravity in front of the centre of pressure. Also, if a shft hits a rock at an angle, the main stress goes to the front part which i near the tip.
Has anybody tried to use shafts with variable diameter - say the first 10-15 cm to be 7-7,5mm and the rest of the shaft to be 6,5 mm?
Greetings: Vov
