Well it's not a room. It's more a big shelf for storing camping stuff and similar things. So the 1-ton anchor was oversized, but 50kgf is definitely very tight, and that's why I am double/triple checking everything. 50kg already takes into account a bunch of safety factors, but I don't want to...

Thanks, I hadn't thought of this additional load on the other anchors. Actually, wouldn't it then be better if I cut the wall plate between anchors 6 and 7, thereby removing is additional load? The thing is that I can live with a maximum load of 40kgf per anchor, but 20kgf is probably too...

But in practice, the anchors are also not perfectly rigid. So if I put weight on anchors 1 to 6, then these would bend slightly downwards. Wouldn't this bring some weight off them and onto 7 and 8? Isn't there any nice software I can play with? Besides my garage project, I find this an...

I see, so almost impossible to estimate precisely, right? I guess the safe option is then to ignore the existence of the anchors that are beyond the rightmost joist. What do you think? Other than that I still have a question. Back to the idealized case of the perfectly rigid wall plate. If...

but wait, if we assume it's perfectly rigid, shouldn't the weight be uniformly distributed across all anchors?

Thanks Jack. This means that if, for example, the leftmost joist is at the midpoint between the first two anchors, the second mid-way between the second and the third, and so on, until the 5, mid-way between the 5th and the 6th, and then there are two more anchors further to the right. We have...

Hi, no it does not. This is a DIY addition we're making for the purpose of adding some storage space. I thought it would be a relatively common mechanical engineering problem although I do not have the tools to solve it on my own. My computer engineering syllabus excluded construction sciences...

Hi all, I am not sure this is the right forum, but I guess my question fits better here than in classical physics. I am building a lightweight flooring in my utility room to store some "not very heavy" items. Two years back when my house was being finished, I installed two wooden wall plates...

Thanks for the link, according to the article: My cable is not even broken in two. If anything it has a crack at some point. So I guess any leaking light would be scattered and not in laser form. Is this right?

Hi all, I was not sure where to post this, so feel free to move the thread if the forum is not the most appropriate. I was reading about safety in fiber optics and the fact that one should not be staring into a fiber optic cable to avoid eye damage. That's pretty obvious, but it also raises a...
