Yeah you could simplify it KootK but that's not entirely accurate.
Rb1957, I'm not sure either. I though the solution might be to use vectors and coordinates, like how you would have a mass hanging from three cables in a 3D co-ordinate. Not entirely sure though.
Hi all,
I've been doing some checking of some older fabricated trestles at work to check load ratings etc. See the attached image for a welding trestle. I have been using FEA so we have a report record etc. Anyways, so far all have been 2D planar members for legs - as in if you look at the end...
Yeah that's fair enough. Reason I ask is particularly in Australia, every man and his dog make their own tray. Generally they are over designed so there may be no reason to worry about dodgy engineering as such.
So basically you are just doing the general checks with live and dead loads to make...
Hey Greg,
Yeah they definitely do. What I was trying to ask/find out is - is there a baseline that all tray manufacturers have to design to? Certain load cases, minium safety factors etc. Like we do for any other design. The ADR seem to not include detail like this.
Hi all.
Does anyone know of any design requirements and load factors to be used for ute tray design, particularly in Australia? I haven't found any ADR documents which outline anything specifically for ute trays. I have found VBS 1 which has a lot of the design and loading requirements for...
Just for your interest that salary is comparable to salaries in Australia. 2-4 years graduated and in the engineering profession you can expect 70-80k Aus Dollar a year. So roughly comparable to what you're on
Human, I've never actually heard of the span to depth ratio. That sounds too good to be true! It does make sense though.
Yeah very true, but is also worthwhile going through the checks myself to familiarise myself with it all too.
Human909, yeah I am an engineer in Australia working under a Registered Professional engineer in Australia. I respect your blunt response and I get that it matters. But I am here trying to learn and better myself. I haven't had to do statics in years hence why I am revising and giving this a...
Steveh49, I was initially confused about your comment.I suppose in real world practice a person standing on grating can't just stand on the load bars and not the gaps, so the load would be applied over an area. So using the total area to find the total force does make sense. Or I can find the...
Human, you're right, a UDL would be more accurate. I can work out pressure per load bar and work out force per metre. Forgive my ignorance, but what factors are you talking about? Sounds like I need to read more of AS1170 [bigsmile] I am an engineer just never designed platforms/structures...
Hi all,
I am design a platform which will have grating supported on two I-beams which are then connected to columns etc. I will be using either steel grating or FRP from Webforge (this stuff is pretty standard in Australia). Selecting the grating is easy - the manufacturer has load tables and...
Hi all, I have recently graduated from university as a mechanical engineer. For my first year after (and throughout uni) I had been doing general drafting work. Now I am beginning to do actual engineering design and am required to design to Australian standards. Particularly AS4100 and AS1170...
Hi all,
Apologies for the late reply.
Thank for all you information and posts - I definitely have a lot to think about now. In terms of dimensions I have changed slightly to an OD of 1.65 metres and will be utilizing either 1.6mm or 2mm stainless. Regarding the different methods, I would just...
Hi all,
I am attempting to make a non-truncated cone with a very shallow taper/slant angle. My knowledge of fabrication methods and processes is not up to par and, thus, I am curious about how this cone as shown in my attached pictures would be fabricated.
Firstly, is it possible to fabricate...
