Thanks Simon for your help and patience. 1. Composite COGs: For Ma = 100 lbs, Mb = 25 lbs, y = 10, I see the equation you suggest, mA(y-x)=mBx, gives a significantly different answer (8) than my proposed formula: (Y)*(MassB/MassA) which gives (7.5). Thanks for that correction. 2. Placing...

Simon, Thanks very much for helping. I am not sure where to go from here. Let's look at the two examples separately. 1. Placing Boat on Trailer: Let's say I have taken a 2" wide sling around the bottom of the 14' boat and hoisted upward to determine the point on the boat where it balances...
