fricked or F--ed means weird, or without merit. That's pretty interesting though, a call to humbleness I suppose.

You remind me of Dr. Selleck from Irobot, "My responses are limited, you must ask the right question" Welp, I'm pretty sure it'll be strong enough, I'll just test my design under controlled circumstances to be sure. Also, your profile pic is so fricked, why is it so fricked? "that detective...

Me and Susan sure do disagree, the only answers I find interesting are the ones that answer my question. Indeed I am trying to design an airframe that must withstand dynamic loads, so this isn't an equilibrium problem, but a dynamic one I suppose. Here I've added the force of the weight of...

You're right, but this is similar stuff we talked about in the other thread though, we need to keep on a different subject otherwise the mods will take it down. Regarding welding, I've rechecked my analysis of my little project and the force that's caused bending will actually be smaller than...

well that's ok, but wait a second, so if the beam weren't weightless, then the 10 N forces would matter because there was inertia. How would we proceed then..?

That makes so much SENSE!!! THANK YOU, but was my calculation procedure correct?

Like this? But why doesn't the 10 N on both sides play a role?

Hello all, I'm trying to understand the maximum moment on a free beam. Consider a tail sitter drone that is simplified into being a beam with two motors fitted with propellers on the end of the beam (see the photo below), let the payload be estimated as two, 2 newton loads going downwards. If...

I see...the strength of the weld has to matter here, back to the example of the full perimeter weld as in the photo. We can only assume this as one homogenous section so long as each seam can resist the shear stress, I'm reading my own mechanics of materials book on it right now but I suppose we...

Hm, I thought so too. I read through your 80's book until page 112, it did help me to better conceptualize this concept. I like what you said, "the welding creates a path to for the shear flow..", this makes me think that it is the weld being placed all the way at the bottom and top of the plate...

L, one more question for you, what if you didn't weld directly around the perimeter, but instead welded a perimeter smaller than the total height and width of the second plate like in this photo? You wouldn't be able to then consider it as one piece then right?

Actually wait! I have one more question. What if you didn't weld directly around the perimeter, but instead welded a perimeter smaller than the total height and width of the second plate like in this photo? You wouldn't be able to then consider it as one piece then right?

I see, well thanks for your help.

Thank you for the links L, I really appreciate them. In the first link however it doesn't say anything about welded plates equating to one solid piece. I want to understand why it is that this first and second plate in my example can become as load bearing as a genuine fused and homogenous 2" x...

I bought an Ender 3 3-D printer for like $290 off amazon, actually ive bought 3 of them, but they're pretty easy to set up. You need a cad program to model what you want to print, someone suggested tinkerCAD and it's probably the best free one you'll get, but if youre a student at university you...
