Hello all,
BS970-1955 lists all mechanical properties for a given steel grade, considering heat treatment processes. For example, it lists UTS and Yield if for a steel if the steel is annealed, normalized, QT, etc.
Is there a standard, textbook, database etc that lists these properties for SAE...
Hello all, I'm looking for a standard and can't confirm that it exists.
ISO 3290 describes the acceptable tolerances of ball bearings themselves (the actual rolling elements). Is there a comparable standard for tapered rolling elements?
I suppose this question first hinges on another:
In general, are a car’s brakes strong enough to lock the wheel?
Given that locking the tire (skidding) is detrimental in terms of stopping distance, and given that a brake system can effectively lock the wheels, is there a benefit to increasing...
"Axial" and "thrust" are synonymous- are one of these actually radial loads (perpendicular to the shaft)?
Are you using a single bearing, or a pair in tandem?
Hello, I'm having trouble reconciling the induced axial loading in a TRB as a result of an applied radial loading. "Essentials of Bearing Concepts" provides a formula using the various contact angles, however bearing manufacturers (SKF, NSK, Timken) all use an equation where Fa=0.5/Y*Fr (the 0.5...
Hello all, thanks for the replies
Regarding my sketch, it was done as though I would not be allowed to install a ledger (hence the long spans).
@LuK13, it turns out I have pockets in my wall. You mention that using these would not be code-compliant, why is that? It would solve all my problems...
Reconvening on this- I put together a sketch of the existing supports, as well as a basic idea of the joists and beams (disregard the validity of this design for now, it is just a basic mockup).
I'm mostly confused as many houses in my (old) neighbourhood have decks of this design, and they are...
Hello,
I'm looking to install a deck to my old brick house- it is not a veneer wall.
Looking at the IRC and DCA6, I can't find any info about attaching a ledger to a true brick wall, just that it is prohibited to attach to a brick veneer.
Am I out of luck here- will I have to make the deck...
Admittedly I don't know if shear will be an issue- would you be able to recommend what topics I should research to learn more on the subject? Similarly, where did you get the 1500 psi value for compressive stress?
Again, I agree with the engineer's assessment- I'm looking for the calculations to determine HOW the assessment (beyond code and intuition).
There is nothing preventing me from replacing this joist, would just like to do the math myself.
Thanks for the reply- I apologize for the lack of clarity and information in my original post.
Firstly, you are correct that this notched would be in compression, not tension- shows how long it's been since I've thought about beam deflection. Regarding the rest of your questions:
The joists...
Hello, I have a floor joist with an enormous notch on it- much larger that acceptable.
Naturally the corrective course of action is to replace it, however I'm curious to determine if bridging this notch is a viable solution. Based on the notch location, the bridge would need to replace the...
