Frequently Asked Questions (FAQ) for Steel Table Design

1. Are loose teeth in a saw blade a safety concern?

The biggest problem with them is that they go missing on modern blades easily, causing kickback. Remember, the teeth are typically soldered on and if they come off, it's most likely going to be at the point of contact with the material you're cutting. I recently had my miter saw kickback. I had bought a cheaper blade and discovered that several teeth had come off. None of the teeth I found were more than a foot from the saw.If you want to reduce the chance of missing teeth, try buying higher quality blades


2. Problem with generating table? closed

Using the S column of siunitx gives you a much cleaner table, the table numbers are properly aligned.The centering command changes the behaviour of the line ending . You need to restore it using arraybackslash. I just defined a new columntype P, so the code is cleaner. But I still think using siunitx gives a result much more pleasing to the eye


3. Looking for a Space marine RPG similar to Starship Troopers (the Novel)

Space Opera by FGU has power armor, personal missile launchers and nukes, the bugs, and as long as you get the Ground and Air Equipment supplement pretty much everything from the novel. It is complicated but just don't use what you don't like. I have for 20 years used it for that setting. The combat rules are actually simple.


4. What pumps necessary for this proposed well water plan?

This is a very common setup, and basically the situation in my house. What you need is called a shallow well jet pump, and I believe this is what you are seeing in the store. Your suspicion is correct - that local mechanic is wrong. Some notes:.


5. How do I remove wobble from my DIY table?

Since the table is wide and not very thick, even were you to correct the issue now, it likely would warp a bit over time -- specifically, the middle of the side with two legs will sink slightly. Therefore, any remedy should be adjustable to compensate for that sag.You could buy and install adjustable furniture levelers, or you could devise your own, depending on the design of the legs.

.. or, for the three back legs, which are out of the way, insert thin siding shingles or similar inclined planes, which can be pushed in as needed (nothing would be needed for the front legs, if you don't mind a slight slant towards the front)


6. Which system to support a grim world of low fantasy? closed

I suggest Low Fantasy Gaming (caveat: I wrote it!). But, it does meet many of the OP's requirements: low magic, martial exploits, injuries, rules light. It is a 1d20 D&D variant however, so it does have classes and levels. Low Fantasy Gaming.


7. Wood legs, steel frame and glasstop design

In my opinion, your question illustrates the first step in designing any project. You have a basic idea and have attempted to solve it as shown in the sketches. The next step (which your question initiates) is to challenge the design concept for viability both structurally and aesthetically. To that end, my comments:Structural considerations:Aesthetic considerations:Next Steps:As you refine your design, feel free to come back for more comments


8. Why is my table going over margins?

In your MWE I made the following changes:With this changes table can fit in one page:Above code can be used also with ltablex as suggest Bernard in his answer. In this case you can increase font size to normalsize.


9. What would happen if a modern model city was found in a fantasy world?

The mages won't go there alone. Imagine they put a baker, his family, and apprentices into the flat above a bakery. He's supposed to provide bread. The baker gets the keys to the flat. He comes in and finds it quite dark. Fortunately an apprentice of a research wizard gives him a quick briefing. This is the light switch. This is the water tap. Electrical cooking range. And so on. Within hours or days, somebody in the building makes a fire in the bathtub and triggers the fire sprinkler.

A working city is a complex system. It relies on people who make it work, from garbage disposal workers to IT service techs


10. Under what circumstances is 5/8" drywall required?

Ancient negligent building inspectors fail to specify that the purpose of drywall is to 'seal' the interior envelope of conditioned (living) space. The idea is to tape ALL abutments and edges of walls & ceilings to prevent air intrusion(s), thus to prevent allowing fire to 'breathe'. Untaped edges/perimeters allow and facilitate a burn danger that cannot be minimized or ignored.


11. Does beam orientation matter for structural engineering calculation values from wood supplier tables?

Absolutely. A beam oriented horizontally has a minor fraction of the rigidity and load-carrying ability as one oriented vertically. Beam strength is largely a function of vertical face height. Cross-sectional area is a minor factor. To demonstrate this to yourself, try bending a sheet of paper laid flat on a table with respect to its width. It can't practically be done. Now try bending it with respect to its thickness. Floppy as can be, right? There's your answer


12. Increasing the stiffnes of a structure by adding stiffener, but at the same time reducing main surface thickness

Wooden tables have been doing that for a long time using an apron. In fact a steel clad wooden surface may be enough. But if you seal the top with a slab of steel you will also want to seal the underside to avoid moisture related warping.

Add a T-profile beam on the underside connecting the supports and your table will be much stiffer.If necessary you can also add a cross shape or some beams connecting the other two beams to add some support in the center


13. horizontal stability of a table

Well, if this were a woodworking question, which it should have been, there are a few standard answers:1) Add an apron, i.e. a frame of boards surrounding the table just below the top. These often have drawers in them.2) Add eight corbels around the base of the table. These are small braces often make to look decorative. They are surprisingly effective.3) Add cross pieces near the bottom of the two shorter sides and add a vertical piece between them the length of the table


14. How to build and run a Skunk Works to weaponize magic flying ships closed

Have everyone who knows about the ships submit their ideas for how to improve the ships. You can tally the ideas to find the most popular ones, and flag unique ideas that may prove useful. Take these results and hand them over to R&D so they can give you feasibility specs on the ideas submitted. Now you have three ships so the three best solutions based on a matrix of advantages, feasibility, and potential developments can be tested simultaneously. Basically use a think tank


15. Implementation of a string-based loot table

If you're going to build a game on this stuff, you better start coding object oriented. Good OO coding naturally manages complexity. Without coherent classes, proper encapsulation, etc. adding game complexity will turn your code base to mush.Strongly typed Dictionary ListStore() has a bug - We don't want duplicatesImplement an Equals(), could be handyEncapsulate the "remainingStorage"


16. Text positioning in multi-column tables

like this?(red lines indicate text area)i reduce your mwe to the part concerning only table. for it i add three packages: ragged2e (for nicer hyphenation of text in table's cells) makecell (for more vertical space around cells' contents) and tabularx (for multi line cells with equal width):remarks:addendum:

from your comment below can be understand, that your table will spam many (at least two) pages. in this case you need:define the first and other table headers (if you like to repeat them on the each page), table foots and the last table foot (see mwe below)note:

begingroup and endgroup is used for limiting some settings (font size, additional vertical space) of table only to this table


17. Could liquid airlocks work?

OK - to continue from my original proposal. Waterglass is interesting in that it is a self sealing solution (pun intended). It could not be used as a part of a heterogeneous method with water due to it's higher density.

One issue that does occur to me is that on exiting the "air" lock then any external view ports or sensors would be covered with a scum of the solute as the solvent evaporated


18. Orderable representation of multi-part values

Your tables look adequate to me. I'd just have a "project_materials" table with columns including "project_id", "material_name", and "material_quantity", but your teacher may not like it. Also, is a "unit" a quantity, or distinct thing, e.g. copper tube, copper screws, pieces of wood in various sizes and shapes?So anyway, for instance:.


19. What kind of cooking knife is this?

After seeing that GIF, I am 99% sure the animator thought up the design by themselves, probably to add some element of interest to the show, but without thinking about the practical side at all. The animation shows the knife being used in a chopping motion, like a cleaver. But here is what a cleaver looks like And this video can be used as a reference for proper use of a cleaver. We see slicing, chopping and rocking motions: knife in the anime is inferior to the cleaver shown above. Considering these design problems, I hope nobody has had the idea of actually produce such a knife and use it in a real kitchen.


20. Wood beams for pallet rack wire decking

You could go with used 12' steel cross members and take them to a fabrication shop and have them cut to length and have mounting plates welded on in order to bolt them to your wall.Or buy the uprights that go with them take them to a fabrication shop and have them cut to length and have the brackets welded on and have the advantage of adjustable height shelving. Pallet RacksIt would not cost to much to have them modified and you can move them or take them with to a new location. Plus you would save space from haveing 2x10 ( or bigger ) wood beams. pallet-rack-beam-capacity-guide


21. Krynnspace two-way gold / steel arbitrage

The reason players can't do that is because it's not fun.Seriously, it's Dungeons & Dragons, not Forex & Forecasting. While in-universe it's a plausible economic development, roleplaying games require players that buy into the premise. The players could also make money by opening a tavern, or just becoming moneylenders after their first dungeon or two. But the game is not about business, it's about adventure. Plus, if it's so easy, someone must have done it before them. There's a reason nobody does it, but I guess it's up to the GM to define WHAT reason that is


22. Why do we increase the minimum beam/slab depth if we increase the grade of the reinforcement to control the deflection

The principle behind that table is that you will be doing a strength calculation in any case and need the table for a guideline of whether deflections or bending strength will be the design driver. High strength reinforcement does not contribute any more to the stiffness than low strength reinforcement, as the elasticity modulus of steel is the same for reinforcement of different strength grades. (If you used a more accurate approach and actually calculated the deflection, the yield strength of the reinforcement would not change the deflection.

)But if you are using low strength reinforcement you will need relatively more or larger rebars to satisfy the strength requirement, resulting in a stiffer beam or slab, which in turn will make it less likely that deflections become the design driver


23. What length can a metal wire (cable) hang vertically?

If I search for 5/8" aircraft wire I can find a product weighing 0.65lb per foot with a strength of 37,000lbs. That gives a length of about 10 miles using the calculation that I assume you used.

The theoretical length of cable that can support its own weight is related to the Specific Strength of the material (aka the strength-to-weight ratio). The linked Wikipedia article gives a table of values for various materials, which I imagine are theoretical limits for a perfect cable.Although not specifically given, the article implies that piano wire could support tens of kilometers of its own length. Other steels (presumably not designed for tensile strength) have breaking lengths of only a few kilometers (e.g., stainless steel, 6km).But nevertheless, these figures are consistent with the result above


24. Is there any link between tensile strength and endurance limit for steel ?

per wikipedia:Typical values of the limit for steels are 1/2 the ultimate tensile strength, to a maximum of 290 you want to rely on such a rule of thumb depends on your application
