Thank you very much that was extremely helpful. think I'm going to give up on the theoretical validation for now :(. Just one final question: How do i convert the mass reading to down 'force' ?
Ok thanks. How could i represent an increase in mass of the car as a force. For example, is the mass increased with a certain angle diffuser by 0.1g how could i deduce the down force from this as the units aren't the same as N?
No worries, thank you for all your advice though. I just have a couple mch more simpler questions. Firstly, in the bernoull equation: Static pressure + dynamic pressure = constant . What exactly is the static pressure- is it atmospheric pressure? Also, how does this shows that velocity is...
This is really basic but say a theoretical downforce of 2.7N is produced, what would be the reading on the scales of this was the case? Would it be 270g?
Sorry i haven't replied for a while, I've been in Germany on a physics trip. In answer to your questions, I'm 17 and the project is being carried out at high school. The model does not have suspension either, it has a curved upper surface to produce downforce and then a flat floor onto which i...
Dick Dastardly...you mean the greatest driver ever :P
I've studied Bernoullis equation quiote intensively but how could i use the conservation of momentum in my calculations?
My setup at the moment is a nitro engine turning a fan of pitch 2.5cm. The tunnel tself is 1m long and the wind...
Ok i guessed so much :(. Thanks for your help though. The reason I'm doing this is for a school project, I've built the wind tunnel and model so i have the dowforce produced but i thought if i could validate the results through a bit of theory it'd improve my project.
Thanks for your help. The reason i ask is I'm trying to find the critical angle for a diffuser on a car to produce the most downforce so being able to work out past which angle the flow separates from the diffuser is key. Do you think it is worth looking into more or am i aiming for somethign...
The context to this question is i wanted to work out the theoretical downforce produced by a diffuser on a car. So can anyone help me in working out the pressure difference underneath a car with and without a diffuser. For additional info, I've set the diffuser at 0.15 rad and 4.3cm(w) 0.7cm(h)...
Hey, sorry if this is posted in the wrong place. Can anyone give me some guidance on how to calculate the theoretical downforce of an upwards curved spolier. Any help will be much appreciated :)
for part b am i correct in using this equation: v=wROOT(A^2-x^2) and if so because max speed is reached at the equilibirum position would i take x as 0?
thanks for you help.
So for the spring constant:
mg=w, 0.01*9.81= 0.0981 which i think is the force extending the spring?
if the spring constant = f/x is so then k = 9.81?
if that's the case then to calculate the period could i use T = 2pi ROOT(m/k)?
Homework Statement
A mass of 10g is suspended from a spring of unstreched length 80cm. The extension produced is 1cm. The mass is pulled down a further 0.5cm and then released. Find:
a) the period of motion
b)the maximum speed of the mass
c) the max Ke of the mass
d)the tension in the...
