Hi there! If anyone out there knows fluid mechs... please help out. Simple question on the stability of a floating body; has to do with the meta-centric height etc. I was supposed to find the minimum mass which could be placed on top of a barge without causing it to lose stability; so I just set the equations with metacentric height equal to zero. All I need to know is if acquiring a non-real solution is something 'common'? Cause that's what I got. And if it is, then pls let me know what I shud do. If it is not something 'common', then ignore this thread. I probably did something wrong; I'll just look through it again. I WOULD post the question and my answer, but its a lot to type. And me not knowing how to use latex... thanks for reading.
