What does the European standard for cookware say about lid design and force?

AI Thread Summary
The European standard for cookware specifies that a lid must be removable from the pot using a force equal to the lid's weight plus an additional 2 Newtons at a temperature of 23°C ± 5°C. This means that the design should allow for easy lid removal without excessive force. Understanding Newtons is crucial, as it measures force; thus, the total force required is the lid's weight plus 2N. This standard ensures safety and usability in cookware design. Clarification on this point is essential for compliance in the trading of cookware products.

Hi all, I'm new to this forum. I just joined the forum and I hope that you guys could help me out.

I'm in the trading business of cookware. I'm currently studying the European standards for these items and there's a point in the standard that I don't understand at all.

It says:
The design of the lid shall be such that it shall be possible to remove it from the body using a force equal to the weight of the lid +2N in any position at a temperature of 23C +/=5C.

It may sounds stupid to you but I'm not a scentist and certainly not very good at Maths. I believe that N stands for Newton but I do not have a clue of what it means be "using a force equal to the weight of the lid +2N."

I have a meeting coming up next week and your help would be highly appreciated. Thank you so much for your help!

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
