Hi,
I know a little about silicones from doing hobby stuff. They usually express the hardness on the Shore Scale (Durometer) Hardness. If you Google the term you get an overview of the different types. The high end of Shore A, silicones, goes as hard as "a shopping cart wheel".
Hey,
Thank you for your help.
I looked at it again and I think I get what you guys are saying now. Since there is a counter force, there must be friction between wheel/leg and the obstacle. Would it be plausible saying Fw=Ft=Fn*mu ? That would give me an extra equation and might make it...
Hi hutchphd,
Thanks for your reply. I'm mostly looking for someone checking my deductions and some feedback and this is very helpful. I didn't think about the effect of the length of d yet, I thought it was more about the tangent force having a smaller angle wrt the interface. I should look...
Stiffness would be the most important parameter, I'd say. By your sketch, Fn/(L0-Ln) should match your requirement of (10*0.454*9.81)/0.01m. (Here converted to N/m)
Hi Kyouran, thanks for taking the time.
Yes, I am assuming no friction or slippage. But I was also assuming there would be a tangent reaction force in A? I figured the wheel would be pushing against the surface, causing a counter moment against the torque. Isn't that the same as if the wheel...
Hello,
I'm doing an FBD exercise and I'm hoping you guys and girls can give me some feedback. I've already done a lot, but I'm not completely sure about it and since it's part of my Msc Thesis, it's important that I get it right. After setting up the FBDs, I get 5 equations and 6 unknown...
