okay, can I ask the last question is shear stress can be calculated by shear flow/thickness?

i can't find any links that i can read about that, that why I came to ask here

but i just can't find how to do that process

im just curious when we get the maximum from the shear force diagram but how to know that that is the load that beam can withstand so we have to compare the stress with the beam material shear strength right

how to calculate shear stress using shear flow

we do not suppose to use the truss method right?

I mean it's not HW but at least can you guide me on how to calculate for its, or that least which method should be used to solve this. it's not truss right?

I have just been asked to find the maximum load of the structure. the section that I draw is the base which will attach with another part. but the load is just the weight of the structure that will be weld to it again.

I just want to know the maximum load of it, maybe with the factor of safety =2

how to find a maximum load on a steel square tube that has one fixed end to the wall and another end is hanging free. suppose the beam is 2230 mm long and the load is applied on the beam on the free end w= 1040 mm. but there also a steel square tube that welded to the middle of the beam and...
