Hi ChrisVer I have the volatge when t is at 0 to be 71v The voltage when t = 5 ms -71v The question 10.6 The time to reach the gretaest voltage rate of change- note the greatest rate of change - note that the greatest rate of change is when dv/dt is a maximum, ie d^2v/dt^2 = 0 10.7 The...

The questions i have got are the same as I've written calculus integration. Thanks

Hi steamking If it's against Pf forum rules you can email me its vinto2@aol.com thanks

So what your saying is the units just change over ie n-m = m-n

So N-m being the denominator makes it be multiplied to N-M^2 end up as the numerator. Sorry I don't get this ? maybe I need to sit down with someone and get this covered as I am running out of time. Thanks for your help and patience.

Morning SteamKing Are you talking about seeing it like this 1/1000 n-m^2 ? If not I am not sure what to do if this isn't correct. I

10^3N-m / 10^6N/^2 = 0.001n-m 0r 0.000001n-m^2 after its sqt Not sure this is correct not done nothing like this before

Hi SteamKing 1 pascal = 1 m ^-1 kg s^-2

It's made up of N for Newton M for metre kg kilogram s second

Yes internal stress, young modulus and ulltimate tensile strength.

I understand that this is why I have showed all of my workings for the first 4 parts of the question. Mpa is a unit measure of pressure.

I don't know that is why I guessed ? I'm not sure what the units would be this is why I'm using this forum for help.

Correct that was a guess. But to be honest I'm not sure how the units would work out.

Kn/m^2
