This is the 4th comment posted in this thread without any sort of constructive answer. Two "mentors" have jumped straight onto this thread with two separate issues. It seems "mentors" on this site or more concerned with rules and regulations than helping people. Mark44 posted problem here is...

Mark44...the fact that the roots are incorrect is irrelevant. My question is clearly asking how to treat a polynomial of this structure. Your response is therefore uselss

Well its work. I am doing it at home. Your issue is pedantic.

Find roots of: I need to set =0 then factorise. I know that this polynomial has coefficients of 1,2,4,8 and there is a rule to factorise this however, i don't know it. Also, i believe a high order polynomial will be included in my exams. Are there any other "special" polynomials such as this...

HI, I am studying vibration, came across this in a textbook and can't see the steps taken to substitute e.q 3.5 into 3.3. There is a second derivative x so where does this go, as there is no s^2 either and I can't see how cos was eliminated Cheers

@billy_joule Hey, thanks for your reply. That's a good point. Would i be able to achieve the bead deposition with this method? I should have stated as well in my original question, that ideally this machine should be able to deposit around 1500-300 beads per minute, would this be achievable...

Hi, I have been given a project to design a system that can "bead deposit" thermoplastic. I have found this resource, It is basically an adhesive deposition system used for packaging in industry. So I think this is a good place to start, by trying to create a simplified version of this. I...

Hi, I am working on a university project looking at material deposition systems. i came across a 30 second video on Youtube and i would be really interested to know how this product is achieving the speed and precision shown in the video. If anybody has any suggestions about the technology...

Attempt 139.63-((80sin(37.9))+57.44)*25 = -126.83 This is pretty close to -123.98 but still off, Have i made an error?

Yes I added the moment from point one. For point 5 this is the method I have tried. I don't follow what you are suggesting?

I got the moment by using (UDL x L) x L/2 ?

Would that have to be included in the bending moment diagram? If so, how is the force calculated? And would it be used in the same way as a vertical force e.g F x distance

Yes I appreciate it is fairly difficult to follow. Essentially I have got the bending moments on one side using stiffness matrix method and the used these values and member equilibrium for the rest of the beam. There is a shear force yes, I have tried to account for that, that's why I have used...

This problem has a lot of calculations from the beginning so i have skipped to the part i am stuck with and tried to include relevant information, apologies if i have missed anything. Assume all working is correct as i was given the answers. After carrying out the stiffness matrix method I am...
