Thnak you DaveE for your help

That means that it's impossible to derive the all-pass & min-phase functions from G ?!

it's when the magnitude of G2(jw) =1

Hey everybody! I have put G1 = (1-s)/(2-10s) & G2 = (2-10s)/ (2 +10s) but than I read that all poles and zeroes should be inside the unit circle, and I don't know how to move the Zero S_01 = 1 to the unit circle

Hey Everybody! I was wondering why do we need Stators in compressors and turbine, for instance the goal of compressor is to increase the outlet pressure, so that the combustion is effective, but why we don't put just Rotors and no stators in the compressor (or Turbine).

Homework Statement Homework Equations orthogonality condition: that means that the point of ICR is orthogonal to the velocity Vb and Va The Attempt at a Solution the solution that i found with the problem is: The ICR of the bar is at infinity. the motion of the bar is translational. I think...

What i don't understand is that: if I apply Newton's law on the "Fluid" in order to find the normal force which is equal to the "pressing force exerted by the fluid on the horizontal bottom of the container", I don't get the same result as by using the "hydrostatic force equation"

I think that the container is exerting a normal force on the fluid, and the pressure at the bottom must be : ρg(h+H). I guess the other force must be the "air pressure"?!

Well, beside the weight force, I couldn't find other forces!

The total mass of Mercury 2448kg, the total weight force is 24480N, the area of the base is 0,375 m², the pressure (of the weight) is (24480/0,375)=65280Pa what i did't understand is why the wight force is not equal to the force exerted at the bottom of the container. if we applied Newton's...

Homework Statement In an empty container, having the shape of a Rectangular Parallelepiped, with width l=0.5m and MN=H=0.4m, and NP=L=0.75M. we poureda mass of mercury =2448kg. T0,T1,T2 have the same section which is 0.2 m^2. we give g=10N/kg, and density of mercury u=13.6 g/(cm^3)...

Yep! now i see it, Thank you very much gneill.

Hello! I'm very interested in physics, and relatively new to it. I'm doing a degree in Engineering but interested in shifting the Major to physics. I'm requesting suggestions about scientific paper that EVERY physicist must read in order to get a certain command on the subject. I mean by that...

gneill, Thank you for your reply and i think you're right! but what about the "bridge"? we worked on "Wheatstone bridge" which looks like that: https://www.electronics-tutorials.ws/wp-content/uploads/2013/10/wheatstone1.gif but i couldn't find similarities with the one that i mentioned earlier!

Hello! I've took a course about Electrical circuits and Networks at the university, and i found out a problem which is uploaded by my professor, and i think he made a mistake! this is the solution i think that the equivalent resistances are wrong (beside Rab), for example if you look at...
