Hi, Is it possible to determine the force (energy) behind a 300dia blank when under a pressure of 0.5bar and subsequently how far the force (energy) may move the blank which has a mass of 16kg? I know the volume and pressure of the air so can the stored internal energy be approximated by...

I'll agree with that. It is important you get good marks. For me, I won't work hard at something unless it interests me, a paper all on theory and background does not and won't motivate me so ultimately I won't end up with good grades. Got to know you are and how you work.

The OP should be doing what satisfies him. I know lost of people who physically built things for their projects including me. Yes it was a nightmare and very stressful but I don't regret it one bit. It's never been done before, it worked, and I am probably going to end up with a published...

I don't really understand the OP? You want us to give you project ideas? Are they not provided by your university? What areas are you interested in?

Well then it is even easier! PV/t=constant so for state 1, obtain an aswer (this is constant) then rearrange for V and plug in the values for state 2.

You have a gas at two states; let's call it state 1 and state 2. Ideal gas law is pV=mRT where R is universal gas constant of 8314. You have all the parameters for state 1 apart from the mass. Once you know this you will know all the parameters for state 2 apart from the pressure. Plug in...

I'll assume that they want to use the ideal gas law to solve then.

Why are people still replying to this OP? He isn't going to listen and he clearly doesn't understand what engineering i and how it is applied. I too like to learn where things come from to get a better understanding of the problem but I am no mathematician and I'm happy with that. I also...

You need to give a bit more on the problem? What fluid are you using?

Yea that was what I was kinda hoping but as we've gone done this route, i'll roll with it. I have hard time getting to grips with this. Is a mode shape at a single instantaneous point in time, i.e. to use your string example, it is plucked, for each moment in time , there is a mode shape until...

You could yea but that would only make me ask more questions and not answer my OP?

Hi I am using Ansys to find the natural frequency of a structure but this has meant that my understanding of vibrations has become unstuck. When I last studied natural frequencies, it was under free vibration. I formed the impression that one structure can have only one natural frequency...

Thanks for the response. Stuff always clear in your own head! Now that I know they are not understandable, I try to make them clearer. I have attached some images that will hopefully make it clear. From a perspective viewpoint, this is what I want to end up with. From the Side...

Can no one help on this? Am I missing some information?

Hi Not sure if this is simple or not but I can't figure out how to do it! I am designing a surround that will be constructed by folding a sheet of aluminum. I've got the geometry right in 3d but I want to transpose this to a template. Yes I can measure but I want to solve using maths for...
