Ok I understand that. Are you able to give me the generic formula for working it out? I am not sure it f= 1/T applies to this question or not

Hi Mate, what method did you use to calculate the frequency? I'd like to compare it to mine if that is ok

I have calculated V3 to be 294.62sin(1800 pi t + -0.56)V I am confident this is correct but I now need to work out the frequency of the waveform, I believe it may be 900 but I am not too sure if my calculations are correct and I can't find anywhere on line that aids me in this particular instance.

Does anyone have an equation for the resultant density of the composite materials? Having a look around the internet and I can't find anything, there was this one website that gave me a step-by-step but the answers did not match (sciencing.com)

I'm working through the equations and I have a lot of information missing. I have calculated the longitudinal strain to be 0.4mm (4/90) is the lateral strain directly proportional to the longitudinal strain? As I need to work out poisson's ratio in order to calculate Bulk modulus, then youngs...

Hi Chester, Thank you I didn't see this table, the following formula provided me with the correct answer: (3*K-E) / 6K

Hi, Yes I have individually researched Bulk, Young, and Poisson's ratio, but from what I've researched I am not sure how to apply it all to calculate Poisson's ratio with the information I have been given in the question.

Hi, Thanks for your help it finally clicked, but I'm not sure where i am going wrong to have to times my answer by 10 to make it correct. (2.55)(8.885*10^-12)Pi 0.28^2) ___________________________________ This gives me 0.46, I multiply the answer by 10 and it is correct (4.6mm)...

I've never really heard of Young, Bulk, or Poisson's ratio before. I have done some research but I can't seem to find the relationship between the three in order to calculate Poisson's ratio. Could someone please point me in the right direction? Thanks

Hi! Thanks, Also, yes sorry - Dielectric constant of 2.55. The capacitor is constructed with circular plates of radius 28 mm. I saw equations for voltage, magnitude of electric field, capacitance and maximum energy, but not one for calculating the gap required. Or would I need to transpose...

I've been given this question for my TMA2, I've tried looking at the learning material but it gives no information on how to calculate the gap? Does anyone have a formula for this? Or can someone point me in the right direction? Thanks
