Thanks for your reply. Is this method to combine uncertainties typically used in science experiments ?

I have conducted a tensile test on five specimens. I intend to do a linear regression for every set of data and get a value for the slope (modulus of elasticity) and its error by finding the standard deviation (using LINEST function on excel) of the slope. I will now end up with 5 slope values...

Hi, I have been doing some research about imapact toughness of steel and found a paper comparing toughnesses of 4 different steels using the Charpy impact test. The following is a link to the paper mentioned. https://drive.google.com/file/d/0B363OnUPK7-deGJDdkhwVU9SQ2s/view?usp=sharing At...

I kind of lost hope of finding material in greater detail, I will have to see how to go about my literature review now.

Thanks for your reply, I'll try to gather info from various sources then and compare the data myself although I think I will also find it difficult to find the data I require.

Thanks for your help. I have found similar articles/papers before I posted, but I am in search for papers with more in depth discussions about the actual material advantages/disadvantages, testing and comparison to other materials. These articles just barely skim on material details, usually...

What I meant by articles is published scientific material, thanks anyway

What I meant by articles is published scientific material, I am able to find plenty of ordinary articles about chromoly, but I haven't been successful in finding academic, published, scientific papers. I require published material for my dissertation.

I am in search for journal articles/papers regarding the use of chromoly (41xx) or HSS tubes in racing car chassis (space-frame) for a literature review. I wasn't able to find any papers up till now. Any help is greatly appreciated.

I was just seeing this animation of a freewheel clutch: Having the pedals instead of the gear teeth and the rotating shaft as the yellow part, wouldn't it mean that if the shaft is rotating faster than pedals the mentioned pedals wouldn't be doing any work (since the red part would never be...

That's what I was thinking originally, but I was concerned that if the passengers do not cycle at the same rotational velocity then the slower ones would not be doing any work.

So, if I use one like the picture below, and say I apply 3 different torques to 3 different gears on this freewheel, the output torque of the shaft should be the addition of these 3 torques right? I am still unsure how this will allow one of the 'engaged'/used gears to stop rotating while the...

Combining multiple sources with discrete gear sets won't allow the passengers to stop pedaling while other passengers are still cycling.
