 Jun 16 accepted Dynamics question. Please help, exam coming soon Apr 14 comment Dynamics question. Please help, exam coming soon @Qmechanic You're right. I cannot think of a succinct title, can you? Jun 29 comment In hydrostatics, is it possible for the bouancy to be greater than the weight of a body? Oh, sure it was! Jun 29 awarded Scholar Jun 29 comment In hydrostatics, is it possible for the bouancy to be greater than the weight of a body? I don't follow that last hint =/. I've determined $T=0,08N$, though. Jun 29 accepted In hydrostatics, is it possible for the bouancy to be greater than the weight of a body? Jun 29 comment In hydrostatics, is it possible for the bouancy to be greater than the weight of a body? I didn't mean I couldn't draw the FBD. I think I get what you mean - I can consider $T_2+B_2-W_2=0$ for body $1$. Ideal conditions will ensure $T_1=-T_2$. Jun 29 comment In hydrostatics, is it possible for the bouancy to be greater than the weight of a body? But is it legitimate to "separate" the system? If the rope is cut, $1$ will probably float upwards, and $2$ will sink, I suppose. Jun 29 comment why is dark matter the best theory available to explain missing mass problems? @Argus Some empiric evidence has been collected in favour of the dark matter theory. In fact, a specialist even created a "map" of the possile distribution of dark matter in our galaxy, or some bounded space near us, by certain measurements involving light waves and how they were bent by the gravitational field of dark matter. Make some research. Jun 29 asked In hydrostatics, is it possible for the bouancy to be greater than the weight of a body? Jun 22 revised Gravitation and equilibrium (…and similar problems) deleted 116 characters in body Jun 22 comment Gravitation and equilibrium (…and similar problems) I got it. Thanks. Jun 22 awarded Commentator Jun 22 comment Gravitation and equilibrium (…and similar problems) Right. by the way, this is from an introductory course from an university (a basic common course for the exact sciences and engineering factulty.).

Please help, exam coming soon @Ron I'm an absolute rookie here, I can't see things so trivially like you! May 5 comment Dynamics question. Please help, exam coming soon @Ron I see. How would you determine the motion of block $1$ through time? May 4 comment Dynamics question. Please help, exam coming soon @Ron What do you call a "constraint" force? This course is really elementary, so I don't think Lagrangian's will appear. It is basically Cinematics, Vectors, basic Dynamics, rectilinear movement (with constant speed or constant acceleration), and relative movements.
