11 posts held, back to 14 July 2026 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 pageof Telegram’s post history, 20 posts per page.
ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.
ER is defined industry-wide as (forwards + reactions + comments) ÷ views— note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate. It is computed over the 4 of 10 measured posts that carry a reaction reading, and over those same posts' views.

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.
Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.
Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.
Lifetime counters from Telegram’s own channel header, read 14 August 2026 — not the date at the top of this page, which is when the subscriber count was last read. Below Telegram’s rounding threshold, so these counts are exact.
36 reactions across 5 posts, in 1 kind.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| 👍 | 36 | 100.0% |
No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 5 of the 11 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 36reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 11 most recent posts we hold, published 14 July 2026 to 11 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

این مطالب بعد از خواندن کلی مقاله که هوش مصنوعی به آنها دسترسی ندارد اورده شده هست و خلاصه میشود: این مطالب مغایر با استاندارد شوروی بود !!! و همسو با استاندارد آمریکا بعد از رعایت دستورالعملهای جوشکاری: در بارهای استاتیکی: مقاومت جوش و فلز پایه تغییری نمیکند و اگر اندازه جوش مناسب باشد جوش مقاومت بیشتری نسبت به فلز پایه دارد. بارهای دینامیکی: این مبنا برای مهندسان مکانیک هست و همیشه باید بر این مبنا محاسبه صورت گیر…

قابل توجه سازندگان پولی و تراشکارها. اندازه های استاندارد عکسها باید رعایت شوند ولی یک نکته مهم هست که مقدار زاویه تسمه هست که بر اساس قطر پولی هست. در قطرهای کوچک به علت خمش تسمه،شیب تسمه کم میشود و مقدار شیب پولی باید بر اساس آن تراشیده شود و گرنه ممکن است تسمه و پولی ساییده شوند.

سوال: چه موقع یک سازه یا شاسی بعد جوشکاری را باید تنش گیری و تنش پسماند را بعد جوش آزاد کرد؟ مثلا در سازه های بزرگ مثل جرثقیلها و ماشینهای معدنی مثل لودر و بولدوزر ، فیلتر پرس و .... ایا باید این کار را کرد؟ یا فکر کنید دستگاه شما ترک خورده، یا دارید دستگاهی میسازید و باید جوش بدهید ایا برای افزایش مقاومت تنش گیری میکنید یا خیر؟ این به عهده مهندس طراح و محاسب هست او باید نظر بدهد. کسی که از ابتدا قرار هست محاسبه دس…

تازگیا خیلی روتین شده که، جای بلبرینگ که ساییده میشود را جوش داده بعد تراش میدهند. این کار، اگر با عملیات حرارتی انجام نشود باعث میشود که شفت شما ۳ برابر ضعیف تر شوداگر شفت آلیاژی یا کربن دار باشد فاجعه هست در این شرایط بهترین کار تراش کمی از شفت تا حداکثر ۷ میل و گذاشتن بوش پرسی روی آن هست. تراش شفت به اندازه ۷ میل، شفت به قطر ۷۰ میل را تقریبا ۳۰% ضعیف میکند. کسانی که کتاب رو خریده اند با نمودار طراحی شفت میتوانن…

خیلی افراد تماس میگیرن و میگن ایا محاسبات مهندسی رو با هوش مصنوعی انجام بدیم یا خیر؟ هوش مصنوعی به خیلی از منابع و کتب دسترسی ندارد و کتب عمومی شاید کم ارزش دسترسی داشته باشد و بر اساس آن تصمیم میگیرد همچنین تو تحلیلهاش خطاهای خیلی زیادی دارد احتمال ۵۰ درصد فرض را اشتباه بگیرد و حتی تو ضرب و تقسیم اشتباه کند. پیشنهاد اکید میشود تو محاسبات مهم سراغ آنها نروید و اگر میروید از چند تا هوش مصنوعی دیگر استفاده کنید و مقای…

Showing the 11 most recent of 11 posts we hold for @MachineryDesign. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Citation-graph rank — 1,348,714 of 1,350,102entries in the measured graph. A weighted position computed from the forward and mention edges below — republished posts weigh more than named mentions — and recomputed periodically, over the whole graph. Published only as this ordinal position, never as a score: a position is a fact, and a score printed beside one channel’s name would read as a verdict this register does not make. The two counts beneath stay separate for the same reason mentions are never summed with forwards anywhere else on this page — a named-by count costs nothing to manufacture. The top 100 by this measure, or how it is computed.
Named by 1 registered channel — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 14 August 2026 — this entry's latest reading, not the date you are reading this.
