with that in mind, I did the equilibrium of rotation looking to C, from bar AC, getting another equation and finding ##H_A = \frac{90}{7}##, is it correct doing that ?
I don't think I understand how am I supposed to remove one support, could you clarify, please? Meanwhile, I tried to split the structure looking only at the branch AC, can I say that in C there will be only horizontal forces, hence finding that ##V_A = 10 \ kN## ?
First, since A and B are articulated, the moments due to A and B are zero. Now, we may call reaction forces in A, ##V_A## and ##H_A## and in the same way, call the reactions in B as ##V_B## and ##H_B##. With that and Newton's third law, I managed to find three equations (equilibrium of...
We know that ##P(A-) = (95\% \cdot 0.5\% + 5\% \cdot 98.5\% )## and ##P(guilty \ and \ A-) = (95\% \cdot 0.5\%)##, so letter a) is just ##P(guilty \ and \ A-)/P(A-)##.
What I tried to do in letter b) was again using the conditional probability theorem. First calculating the probability that...
So you agree with my part c) calculation ? What about letter b), as told before, I don't think I truly understand what that relative frequency question mean.
so you agree with my calculations in c), but don't agree with the scientist's assumption that the events are independent? And letter b) could you clarify what that relative frequency interpretation mean ?
For letter a), i think that he is assuming that each hypothesis is independent, and that they are mutually exclusive.
For letter b), I understand that it indeed admits the relative frequency interpretation, since the the experiment is being produced several times.
For letter c) we do the...
If anyone can recommend platforms or programs for doing these type of figures and diagrams, even if it doesn't have anything related to latex, I would be gratefull to
When using latex for writing problems in physics, I find it difficult to make diagrams or figures (such as circuits, atwood machines, lenses, ...) so I wonder if anyone has some recommendations of programs or platforms that can make this "drawings" easy, possibly without the necessity of coding...
Oh, now I see, I was messing up things. Using the superposition principle to "complete" a triangle with the center, middle point and edge point, you form a triangle Wich has constant area in a constant magnetic field, so the total induced potencial difference along it's perimeter is zero. This...
