Dear Engineers
I'm working on a rack used for sea transport of some long objects. The objects are stacked in the rack. Please see attached figures.
I'm worried about the influence of hog & sag effects on the rack. Due to this effect, i think i need a longitudinal degree of freedom between the...
Dear engineers
I am working on a concept and cannot give too many details.
Basically its for lifting something up in a windturbine. See left side of IMAGE
During the lift, wind forces may push the lifted object into the tower.
I wish to find the impact force to see if the tower takes damage...
Hi eng-tip readers
I have a large casted steel structure. I will be using high strength machine screws to attach another steel structure onto this casted structure.
Since it is not possible to use nuts, and hence the threads in the casted structure must carry all the bolt load, i am a bit...
Dear fellow engineers
Take a look at this picture: http://i.imgur.com/vObP2HB.png
Description: We have an open 'box' and we weld a plate to the inside of the box, using fillet welds on all edges on both sides. Plate is light blue, and the dashed lines is the plate if the sides of the box was...
Hi eng-tips engineers!
I'm designing a bolted connection for a construction.
I'm quite unsure how to handle this statically indeterminate system shown on the picture below:

I know how to approach single bolt groups which are eccentrically loaded. This i usually do...
The pressure vessel i'm designing is basically a box, i.e. flat plates. And i've understood that WRC107/297 are not applicable for nozzles attached to flat plates (correct me if i'm wrong), soo FEA it is.
The nozzle is welded to the plate. The weld is simply modelled as a straight line. This...
My question is regarding multiple openings. Say I have two openings: One nozzle opening large enough for some opening rule to apply, combined with a small opening, that alone would not need to be taken into account (e.g. a ventilation opening). Would that qualify for multiple openings, e.g...
