So just to provide a quick update, it turns out it's the same construction after all and the solution to both problem are identically are same too he explained. I don't know why he said earlier it's different, it just makes me and other students confused lol.

It's just a symbol and doesn't affect the answer for the t1 and t2 so I don't believe that it's the case. Yes, and I take the biggest shear and tension force acting on one of the bolts and find the core diameter of the bolt required from there. Later I will get an answer from my teacher about...

Ah it's okay :D So my suspicion appears to be true, so if the free body diagrams of both constructions are same, then the diameter of the bolt required and the stresses acting on the weld should be the same right?

Sorry, I thought my title is sufficient, I want to know mainly if these two constructions have the same free-body diagram is correct or not. From the first construction, the textbook provided the free-body diagram as shown above. I tried to draw the free-body diagram from the second construction...

The construction just basically a bracket that is being held in place by welds and bolts and there is a force acting on it. The textbook answered the first construction and the free-body diagram is shown like this below: I apologize for the picture not being in English, here's the...

Yeah, I noticed that when I tried to solve the problem again, thank you for pointing it out though! So the final result would be: ΔD = 3Eh^2/(12(1-v^2)) * Δh + 2Eh^3v/(12(1-v^2)^2) * Δv ΔD = 3E(0,1)^2/(12(1-(0,3)^2)) * (0,002) + 2E(0,1)^3(0,3)/(12(1-(0,3^2)^2) * (0,02) ΔD = 5,4945 * 10^-6 E +...

I'm not sure I follow, but I kind of get what you mean.

Yes, correct.

Apologies, my teacher changed the value of ##\Delta v##, from +-0,02 to +0,02. From examples, to solve the problem I don't need to be adding quadrature. Here is an example:

Attempt at question No. 1: ΔD = ∂D/∂h * Δh + ∂D/∂v * Δv ∂D/∂h = 3Eh^2/(12(1-v^2)) ∂D/∂v = 2Eh^3/(12(1-v^2)^2) Δh = +- 0,002 Δv = 0,02 h = 0,1 v = 0,3 ΔD = 3Eh^2/(12(1-v^2)) * Δh + 2Eh^3/(12(1-v^2)^2) * Δv Because the problem asked for maximum percentage error then I decided to use the...

Ah okay thank you for your help!

Interesting, though I cannot admit that I am able to visualize it. Hmm I don't know actually my Professor doesn't teach me any chord equations. Probably only 1, where if one bowstring is the diameter and the other bowstring cuts perpendicularly, it will cut into two equal lengths. Regarding...

I'm trying to find the distance between the chord to the arc of the circle, see question mark I put on the picture I shared. Sorry if I make you confused.

It should be 10 and it's the sagitta, am I correct? But I'm still not sure how can you come up with that equation though. Yes it's the equation of a circle but, if I'm wording this correctly, where did you derived this equation from? Is it from C = πd? Or A = πr^2? Or even r^2 = x^2 + y^2...

What did you mean by the "distance from c line" sorry? From what point?
