Hey Guys i have tried to attempt some of these questions i just don't understand where to start from i need the main formulas that can help me do these questions thanks alot a) coaxial line consists of an inner conductor of radius RA = 1 cm and outer conductor with an internal radius of RB =...

Hihi, I don't understand what is the meaning that BNC cable transfer high frequency signal? For example, I use BNC cable for the connection between my diode controller to the diode laser. I also use BNC cable to connect my photodiode to the oscilloscope. I'm not sure what is the...

[SOLVED] Tension in two cables Homework Statement 21.0 kg loudspeaker is suspended 2.40 m below the ceiling by two 3.90 m long cables that angle outward at equal angles. The attempt at a solution So my homework comes from the MasteryingPhysics online homework. What I first start out with is...

Homework Statement A strong plank 8.0 m long and having a negligible mass is supported by steel cables from both ends. A jaguar with a weight of 800 N stands 2.0 m from one end. What is the tension force in the cable farthest from the jaguar? a. 120 N b. 200 N c. 240 N d...

hello everybody i have a problem of how I can determine the tesion in three cables required to support a cantilever beam have a distributed load of 302 kg/m

i need some information about parabolic cables (links,books,equations etc.) for my graduation thesis. Thanks

Homework Statement I've included a picture of the problem so you can see the diagram too. The question is asking for the tension of 1 cable, when 2 are given (problem# 41).Homework Equations no equations per se.The Attempt at a Solution I resolved cable AC and cable AD, but don't know how to...

Conductors and co-axial cables!?? Say you have a long conducting hollow cylinder with some surface charge density \rho which is inside another hollow (uncharged) cylinder. What would the electric field be outside the outer cylinder? I am guessing that the e-field outside the outer cylinder...

Homework Statement Ok, I've got three cables all pointing in a downward direction towards the orgin. They all connect at the orgin, onto a 750lb weight. Determine the tensions in A,B,C. I'm going to put these into (x,y,z) form, so you get the picture. A = (4,-2,5) B = (-3,-3,6)...

I'd appreciate help with this problem as I don't know how to start it: A beam with a mass of 1500 kg and a length of 2.0 m hangs from two cables, such that it makes an angle of 65degrees with the vertical. Both of the cables are completely vertical; one is attached at the lower end of the...

Given the tower is 70 m high, and the force of FAB= 2 kN and the x and z components of the vector sum of the forces exerted on the tower by the 3 cables are zero. I have found the lengths of all 3 cables. I have also found the unit vectors for all 3 cables. I just do not know how to find the...

The steel I-beam in the drawing has a weight of 8.90 kN and is being lifted at a constant velocity. What is the tension in each cable attached to its ends? (picture attached) for this problem do i need to first convert kN to N?...and I am just not sure where to start...

Does anyone know where I can get a few 10-pin female flat ribbon cables. They look like this: http://hubbard.engr.scu.edu/embedded/lcd/lfh8p4032b/P1010029.JPG The header looks like this: [ooooo] [ooooo]

First, on an unrelated note, I would like to share an anwser I think I found to be correct on a question I posted here a while back. I asked about how a smooth collar that was Not Pinned could prevent a moment. The problem I was faceing was the fact that in order to have "play" so that the...

I'm a bit stuck on a tension problem, I have a weight supported by three cables. I will have to admit, up to this point, I have been cheating on these tension problems. What I have been doing is writing various equations and using my TI-89 to solve the system of equations. This method has been...

It is the second occurence. In the morning, when i turn on my computer, i figure out that it has around 4-6% battery powe missing. At night, only the ethernet cable (and usb mouse, but i eleminated it as a suspect for the power theft :cool: ) is plugged in. So could be that the thief here is...

Hello again, I'm stuck on a new problem. Again, I thought I had the correct equation but apparently not as my answer is not correct. Here's the problem: A steel I-beam has a weight of 9.10 N and is being lifted at a constant velocity. What is the tension in each cable attached to its ends...

Greetings ! I was searching for this on the web for a couple of days and found practicly nothing. This is highly unfortunate because it means that not only did I not get the info I wanted but I'm also lousy when it comes to such searches (and I was actually of the opposite opinion prior...
