hi mark Thank you for the response, I am still a little unsure to be honest. is it not just fd and v^2 that are proportional therefore the velocity has no affect on drag coefficient? and the same with Reynolds as my understanding is because Reynolds is a function of velocity and we know...

<< Mentor Note: Thread moved from the technical forums, so no Template is used >> hey guys As the title suggests i need a little help with my results from my thermofluids lab, i am trying to come to a conclusion about two of my graphs which are attached. The lab is looking at measuring the...

Thanks very much ill mark this as resolved cheers

okay so I've just re measured them now its only a slight difference but noted down more decimal points does it check out for you. its now within the range of the recomended GPA of each material. sorry if the image is blurry i can zoom in if needed

oh i think that is what the problem is i have just calculated it for 1.3mm thickness and found out that my GPa is now 1.398x10^11 which is pretty close when considering my error percentage. i think I am going to have to measure the thickness again for each one

i used a pair of verniers which measures to a thousanth of a mm but the only problem was the angle at which the verniers gripped the beams. as it did vary from 1mm to 1.3 dependant on the agnle, do you think this could be the issue?

hi chestermiller ah i seee i rounded 0.025 to 0.02, not sure why, it should be 1437480000. the Deflection is in metres i think the table results are unclear. the deflections are on the left. as i have done P0 -P50 etc so with 50 grams on the beam gives a deflection of 1cm or 0.01 mtrs. the...

Yes it is.it is for gravity

Hi chestermiller Thanks for getting back to me so quickly. The variables are L=o.33 W=0.025 T=0.001 All are in metres. We used a simple g clamp and measured from the point of suspension. Hope this clears it up a bit.

Homework Statement hi guys I am conducting an experiment for my coursework in physics and i have come across a bit of a problem. i am trying to calculate the youngs modulus of 3 different metals Aluminium steel and brass. To calculate the modulus of the material i am using a chart of Mass k/g...
