anyone know a value for the coefficient of friction of wood on rubber? rhys

Here's all the data I have: (SG1 and SG2 are the strains recorded on each side of the beam) Compressive Load (kN)..SG1 (µStrain)...SG2 (µStrain) 0........-0.04374...-0.63108 0.047......-8.88919...-11.52479 0.106......-13.40135...-33.98217 0.15......-17.01924...-49.0698...

Well yes, but I only have a very small amount of data, so I can't determine exactly when the member starts to buckle. I know I have to use Hooke's law, but I don't know how to implement it... Is there a graph I can plot that would clearly show when the member buckles?

I have a small problem with a column buckling experiment I've conducted. The rig consisted of an aluminium member tested in compression using an Instron loading machine. Strain gauges were placed on both sides of the member and a computer recorded values of strain at various compressive loads...

Yeah I was playing around with it because I didn't believe my original answer and I came up with 51.9 W/mK too. I'll have to ask my lecturer what happened there. Thanks for the confirmation Rhys

Did I attach the wrong file? Here's the right one. Sorry about that. The equation I quoted takes the thickness into account. Temperature gradient = (T1 - T2)/x If you substitute that back into the last equation I gave, it becomes Fourier's law again. The metal sample is an unknown...

I have attached a problem I am having trouble with in PDF format. Could anyone take a look and tell me what they think please? It's Question 1a part (iii). As far as I can tell, the heat flux through the network should be constant, so Fourier's law for heat conduction gives: q = -kc x...

I have EXACTLY the same problem. I am given a dataset (A) of velocities in volts. I also have a dataset of displacements at time intervals of 1ms over a time period of 2s, giving 2000 readings. Since: x=asin(wt) v=x'=awcos(wt) I thought that I could use the fact that x * (w/tan(wt)) =...
