knuckle joint

[jimmyjimmy]

Hello, I am a student who attends mechanical ing. I was assigned a year work that consists in the design of the production cycle of the components of a hinge joint, in particular the design for fork foundry, my doubt is whether to use a c40 steel or a 39nicrmo4 considering the following dimensions attached.

 

[MassiVonWeizen]

a- what does the material have to do with the size?
b- the material of which components?
c-why do two posts equal?

I agree with stones, the material will be chosen according to the work that must make the piece.
banal example, if you need to perform a heat treatment to harden the piece and contain wear the c40 I do not see it very suitable.
but before that I would do a dimensional verification on the efforts that must support the piece.

the professor clearly indicated that the size depends on the civil or industrial/mechanical use of the piece in addition to considering the type of material with subsequent thermal treatments.
However, forgiving my ignorance I wanted to know whether for the construction of the joint fork on the ground, destined to an industrial application sector, the use of a steel such as the c40

 

[TECNOMODEL]

can you clarify the speech of civil or industrial/mechanical use?
because if it is of a certain size would be precluded one or the other scope?

 

[jimmyjimmy]

to simplify, you a fork of an industrial joint of what material would you do?

 

[TECNOMODEL]

If I don't know what stresses any response would be a castronate.
I could tell you aluminum as the best structural steel and would always be a correct and wrong answer at the same time.
and however it is who designs that chooses the material, if that joint has already been designed will be indicated in which material is made.

I think it's pretty shitty.
the scope of use of a component is not determined by the size. it is established by its function.
do you think that in the civil field you use a fervour that bends it with the grissino and in the mechanical field you have to use the adamantio?
and the mechanics of the tankers, to say, how big do you think it is? there will be pins from one meter of diameter, big pins like a man or more, the screws will be from m100....

I wouldn't even use the fork to spread the cloth. However, it is not true that the dimensions induce the industrial or civil sphere. for my experience in industrial mechanics will never use such a thing. If you ever use it to pull a roof, a canopy, a bridge.... so if it is for civil areas it can be that it has to resist more static loads than dynamic, therefore it would not need a alloy steel and it would be enough a c40.
fusion on the ground...it would not be the most suitable for such small and cuzzy details however if you can do it, half above and half below the split plan of the two boxes with inside the soul in the hole of the fork.
