[quote=smfinley][quote]VERY SIMPLIFIED 225 lb sitting on the end of an 8' lever yields 225lb x 8' = 1800 On the wire, lets assume his centre of mass is 4 feet further out, & he keeps the hull just on the water, horizontal for our purpose, we now have: 225lb x 12' = 2700 What force would it take on an 8' teeter totter to balance the 225 lb kid sitting 12' out? 2700/8 = 337.5 And you guys thought math & physics were boring [/quote] EC your simplified answer looks very similar to mine from earlier yesterday also. [quote]Another explanation, same answer as Steve. If you assumed an 8 foot beam, that your center of mass is 4 feet from your feet, and the boat is level..... You could take your weight x current distance from leeward hull / alternate distance from leeward hull. 225*12/8 = 337.5[/quote] I think the real answer is to many engineers on one forum discussing boats. I am an Electrical Engineer so all these forces are over rated ;-) [/quote]
