I was wondering where I could get separate CEE 7/7 plugs?
Separate because I want to connect them to burial cable, so cutting off connectors from existing power cords is not an option.
So far I only found http://www.stayonline.com/detail.aspx?ID=11520" , but they charge 45$ for shipping...
Isn’t friction different from rolling resistance or is it common practice to mix these terms?
Also, those calculations happened without taking the radius into account as the radius of their ball is constant.
I’m sure you’re correct about this, maybe you also know an online source where I could get an understanding of why this is the case?
Also, when I multiply the rolling resistance force with b then I get [(mw + mp)*g*b2]/r
I hope I can find...
In https://www.physicsforums.com/showthread.php?p=2137841" I'm looking for a maximum rather than an average, sorry for not having mentioned that.
May I ask what you mean with "it"?
rolling resistance coefficient of aluminun on lawn
I am looking for the rolling resistance coefficient of aluminum on lawn, I assume I won't find this in a table?
I was wondering whether there are there other ways to find this coefficient, other than making an aluminum wheel and rolling it...
This is how I would have calculated the moment created by the person: mp*g*cosα*c
I’m not sure whether I understood the rolling resistance thing very well, you said you “made it act”, can this be done? (assuming you meant r rather than b)
Also, overcoming the rolling resistance isn’t that the...
Thanks a lot, I think we’re getting there!
I have a few more questions though:
- Isn’t there any angular momentum resulting from the transition from diagram two to three?
- Shouldn’t c be the length of the line between the CM of the person and the ground contact point and shouldn’t gravity...
(mw.xw - mp.xp) / (mw + mp) = 0 is the formula to find the x-component of the combined centre of mass, I took the dotted line as y-axis, so when the x-component is zero we’re at the tipping point.
a and b are not yet defined because I’ll first have to decide on the thickness of the materials...
I was wondering whether Simulink could help me solve https://www.physicsforums.com/showthread.php?t=301390"?
I would prefer to stay with SolidWorks because I already use it for 3D modeling so I guess it will be easier to learn, but I don't think CosmosWorks could do that.
What do you...
Thanks for the advice! I could flare the outer rims when the resting surface needs to be a few centimetres wider to achieve balance, I’m just a bit concerned about the price tag and the loss of support for the mesh. I’ll also keep the perforations in the metal mesh smaller than the smallest...
Dear all,
Above is a proposal for a human wheel I would like to make, the inner cylinder would be perforated, similar to http://boards.core77.com/viewtopic.php?t=18087 . The difference with a hamster wheel is that it wouldn’t be stationary and is able to take ( large ) bends. The ribs seem...
