Hi, ok, so the task is to define the thickness of th weld, the so-called a-dimension. If the welds were either vertical or horizontal, I'd have no problem, but they're not. So do I divide the force into components or perhaps the welds? What about how to calculate the moment caused by the force...
Wow! You really put time and effort into this, THANKS! That method of considering ds/dt as one object is great. You also helped pinpoint my original probem:
Why is it marked differently above and below?
Once again, THANKS A 10^6!
I'd be glad if anyone could help me out here. I guess this is closer related to maths, but in any case there is dynamics behind it. So when we want to express acceleration a using displacement s, , it looks like this, right? a = d^2s/dt^2. What I don't understand is that if you substitute v...
Hello. I'm sort of confused about when you can integrate... Say for example if you have dx you're sort of integrating a "hidden" constant, right? So you increase the power by one and either use the upper and lower limit or just add c: x+c. And similarly if you have xdx, again you increase the...
I have asked this question from dozens of people in numerous phorums, but you are the first person that has been able to answer me so that I understand it! A thousand thanks.
That's what I thought, so I was misled at another forum. however i don't understand why the supporting force of the ground is not taken into account when calculating the compression of the spring? In other words, why is the force at one end of the spring(box weight) taken into account but the...
But several websites state that the reaction force must be directed at a different object than the actual force. E.g. if i push a wall the wall pushes me. That is an action-reaction pair, right? In the case of the spring both the weight of the box and the ground act on the same object, the...
Hello everyone
I'm quite confused here and would really appreciate help.
Consider a spring standing upright with a box on top of it. Now according to statics there are two forces acting on the spring: the weight of the box G and the support of the ground -F. But when we calcuate the...

You're really putting time into this guys! And I think I finally might be starting to accept the truth as it is:) The goats and the money really helped!
Thanks for trying!:) I've already considered both of the examples that you mentioned but I just think the result should again be two "pulls" because their are two "pulls" acting on the rope. But hey, maybe some rainy day I'll finally get it...
