Hello :) I am currently confused about the forces acting on particulate matter in a cylindrical bin. It is apparently widely accepted that the vertical forces acting on an elemental slice of particulate solids in a cylindrical bin are: The pressure difference between the bottom and the...

Ok thanks a lot for your help vela!

Ok thanks. Representing the voltage as a complex quantity: E_{ab}=10e^{\frac{\pi}{6}j}e^{j\omega t}=-20I_{1} E_{ab}=10e^{\frac{\pi}{6}j}e^{j\omega t}=60jI_{2} E_{ab} + E_A=10e^{\frac{\pi}{6}j}e^{j\omega t}+20e^{\frac{\pi}{4}j}e^{j\omega t}=-30jI_{3}

So, with this new understanding, I think the KVL equations are: E_{ab}=10 \cos(\omega t+30^\circ) = -20*I1 E_{ab}=10 \cos(\omega t+30^\circ) = 60*j*I2 E_{ab} + E_A= 10 \cos(\omega t+30^\circ) + 20 \cos(\omega t+45^\circ) = -30*-j*I3 = 30*j*I3 Which can then be solved to obtain...

Both the things you said make sense. Thanks vela!

Homework Statement I am required to write KVL circuit equations for the following circuit I don't need to finish solving for I1, I2, I3 and I4 at the moment. I just need a bit of help setting up the equations. Thanks. Homework Equations Kirchoff's Voltage Law, which states that...

Ok, thanks for your help.

Okay thanks for that Dick. So if I would like to write the second integral of f(x), is it the proper notation to write it as \int{\int{f(x)d^2 x^2} ?

Edit: Sorry had trouble with the equation editing

Thanks that helps a lot!

Yes, A, B and C are horizontal forces. If the frictional reaction force is sufficient to prevent slippage, does that mean it is equal to (the sum of the forces at that point on the wheel resulting from the torques) + (the sum of the horizontal forces)? Or is it only the sum of the forces...

Hi, this isn't a homework question, I'm just curious about this. I am wondering what the correct notation is for the integral of F(x). For example, integral of f''(x) = f'(x) + c integral of f'(x) = f(x) + d integral of f(x) = F(x) + e integral of F(x) = ?? I feel silly for not...

Homework Statement This is just a little part to a bigger problem I am having trouble with. I have simplified it to get to the point. In the free body diagram shown, I would like to find the value of the horizontal reaction force (RH) applied to the wheel from the surface, assuming there is...

Thanks rock.freak667!

This isn't a homework question, just something I was wondering about, and this seemed like the most appropriate place to post it because of its simplicity. When integrating a function of the form f(x)=(x-a)^{n}, I find I get a different result if I expand the brackets first and then...
