DTGT2002 - Yes that is correct.
TLHS - We have a good relationship. It saves him a little bit of time, me doing the calcs/reviewing the codes, and it saves the company money and allows me to document my hours to eventually get my PE. Yes he does review all of the codes, he is licensed in all 50...
The company I work for sold some aluminum temporary shoring equipment to a company in Canada. All of our products' tabulated data is stamped by a PE in the US but does not have stamps for any provinces in Canada. I am working with a PE that is licensed in the province where the equipment was...
Dhengr, you are correct, the pipe does stand vertically and there is a slew bearing on top of the pipe. I have a couple different setups that I chose basically from aesthetics only. I have a 2 roller set up, top and bottom, for light loads on small dia. Pipe with relatively thick walls compared...
I have a pipe that is fixed to a base plate and the base plate is anchored to a concrete floor. There are a set of rollers at the top of the pipe (the end furthest from the anchored end) and a second roller set on the opposite side of the pipe anywhere from 48" to 70" below the top roller set...
It's liquid cooled and the same exact problem can run in 2016 and does fine. We have monitored everything up until the point it shuts off and nothing seems out of ordinary. My workstation is 100x better than my laptop and my laptop can run the same simulations without issue. The only way this...
Whenever I try to run a simulation in Solidworks 2017 or 2018, my computer shuts down at random times while the problem is running. On the same computer, I can run the same simulation in 2016 and it runs fine. The only issue with using 2016 is all of our models have been updated to 2018 format...
jgKRI-Already used FEA to evaluate the system. I was just hoping to learn a way to do this by hand. Thanks!
thaidavid40-This is just a design. We have similar jibs with close to the same track design but this was designed with a newly proposed heavier aluminum extrusion, so no test data for...
Thanks for the response. I'm not concerned with the track opening up to the point that the trolley drops out but I would like to find a way to calculate the distance the portion of the track the trolley rides on spreads open. I'm concerned with the push pull force of the trolley increasing as...
I have an aluminum jib track design that I need to find the maximum capacity for. If it was an I beam or a more standard track this would be simple but it is a patented enclosed track and I can't find any help on this subject. I have attached a PDF showing the design. Figure 1 just shows the...
Thank you Kenat. Your links provided me with exactly what I needed. What i meant was with the tools available at our shop, the plate is as smooth as it is going to get.
The metal plate was machined flat and as smooth as possible. The max pressure is only about 40 PSI. The velocity is negligible. The same design worked amazing in a previous project but the pressure was a little less than half of the current requirement. I'm just surprised in the drastic...
I am using a steel plate resting on a teflon disk in place of a slew bearing. The material in contact with the teflon is steel. I know that the co-efficient of friction for teflon on steel is pretty low but is there any type of lubricant that would make it even lower? I have looked and looked...
The difference between the beam he wants to use vs. the beam I selected is his is a combination W+C shape and mine is just a W. All the calculations check out. The issue is the added labor to weld the cap and added cost of materials. I'm not trying to see who is wright and who is wrong, I was...
The moment equation, F2-1 includes Fcr (F2-4) which incorporates Cb. The reasoning he gave me is that after the plot stops the beam twists too much. That's where I became really confused because I thought that is what the LTB equations considered. He is a super smart guy and I have the utmost...
