Free Body Diagram of a Fish Swimming

AI Thread Summary
The discussion centers on creating a free body diagram for a swimming fish, with the original poster struggling to find relevant resources. Participants suggest that understanding fluid pressure and buoyancy is crucial for accurately depicting the forces acting on the fish. They note that the forces affecting a fish are similar to those on a person swimming. Additionally, they encourage using educated guesses if specific information is lacking. Overall, the conversation emphasizes the importance of recognizing the relevant forces in aquatic movement.

I have this project to do; it's of a free body diagram of a swimming fish. But I can't seem to find any good sites that give much info about a fish swimming. All the sites come up as a fish out of water, or a person swimming. Does anyone know sites that may help, or the forces that act on the fish?

Thanks!

Have you talked about fluid pressure or buoyancy in your course yet? That will be important in working out the force diagram. What one force do you know has to be acting on the fish?
 
The forces on a person swimming will be the same as a fish. Failing that its pretty easy to guess.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
