If You Feel Insecure And Don't Know How To Rise Up Your Quality Of Life. Please Read The Biography Someone

Ini hari jumat, Alhamdullilah ya Allah 🧘‍♀️

Well, karena work from home ini, saya jadi lebih sering menghabiskan waktu saya untuk gadget dan inter-connection saya untuk keperluan hobi dan sekaligus profesi. Disini yang saya tekankan adalah dalam mencoba watercolor digital menggunakan Ipad. Hal yang membuat saya bertanya-tantya akhir-akhir ini tentang ketahanan sebuah kota. Dengan segala hiruk pikuknya dan dengan segala macam masalah sosial ekonominya ? Akankah bisa ?

Bertahanlah dan semoga selalu dibuat mudah oleh Allah heheh

Do’a sang Nabi

اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ البَرَصِ ، وَالجُنُونِ ، والجُذَامِ ، وَسَيِّيءِ الأسْقَامِ

Ya Allah, sesungguhnya aku berlindung kepada-Mu dari penyakit belang, gila, kusta, dan dari keburukan

(HR. Abu Daud)

Like I'm dying when i forced myself for more patient and less complaining 😔

Yuk bisa yuk mbak nisaa 🥰

I asked Allah SWT

In a quite evening at the beginning of a gloomy day

Suddenly I sculpting by a horrible notification

Oh Allah, is not the first time

It has been a quite often

Until I felt that I should give up

By the way, perhaps is not kind of a big deal

But

I just exhauted.

I freeze e I lose hope

Im so hopeless until my soul freezed

Unease that all I felt

I pushed myself to beg Allah

Rised me up by

Istigfar All rest of day.

And I pulled myself up out

I eager to Move just make action event

10 percent posibility

But i believed in Allah SWT.

He will always help me who begged always

And Alhamdullilah I got

ALLAH IS AMAZING

Don't be loose Hope not be sad 🤲.

The Art of Structure Engineering: Thomas Telford Bridges

The structure engineering was so powerful, they construct and design everything with efficient cost and elegance appearance. The combination of art and engineer or we can also be called it a combination of civil engineering and architecture engineer.

Chiefly, This section I want to discuss Great Britain and study the works

of Thomas Telford, and also two other men named Stephenson and Burnell.

I'm going to begin each section by defining some section goals and in this section,

the goals are to show how the definition and ideals of structural art began,

and as I mentioned, they began in Great Britain, Thomas Telford and also contrast the early of the iron bridge.

Come up with 3 collaboration in 3 aspects to analyses and give critique both the technical

and aesthetic aspects of the bridge design, These are efficient, elegance, and also the economy. The relation between 3 aspects shown by the picture below.

So with these changes, from the scientific point of view, we have a new material that is born

of the Industrial Revolution-iron. This revolution. From a social point of view, we have a new opportunity, industrialization. And from the symbolic point of view, we have a new vision, a new form for structures that we define as structural art. Before we going into so far, we should be understanding several keys to helping us understand,

 Ambiguous Form: Unclear how the forces are being carried

Cable : Structural element to resist tension only

Cantilever : a protruding rigid structural element, such as a beam or girder, anchored only at one end

Compression: application of inward forces to different points

Density : Mass per unit volume

Span : longest unsupported length

Spandrel: The planar like structure that connects the arch to the deck

Suspenders: vertical members suspending the deck, or carrying the loads to the main cable

Tension : Describes the pulling force exerted by each end of a road, truss member, or similar three dimensional object

 The raised of Iron-bridge, started by the regulation in the UK, One is we have Queen Elizabeth who outlaws woodcutting, the forests in Great Britain are getting diluted, So the Queen outlawed wood cutting. Moreover, Britain was adjusted free enterprise

Next, British Democracy encourages free enterprise. Britain wasn't really run from London.

The transportation system in Great Britain was pretty bad. And finally, island isolation provides political stability Great Britain avoided wars on Continental Europe and they hadn't been invaded for about 700 years. Therefore, there was a sense of security. So very briefly, that is the social context surrounding Great Britain and what allowed structural art to flourish in particular in Great Britain at that time. And the famous structural engineer of this era was Thomas Telford; born 1757, died 1834.

 THOMAS TELFORD  

 Thomas Telford; born 1757, died 1834. Now let's take a look at Thomas Telford's later works.

We started to look at the Craigellachie Bridge completed in 1814 spanning 150 feet.

Next, we're going to look at the Mythe Bridge completed in 1824 at about the same span, 170-foot span. And then finally the Menai Bridge completed in 1826. This is not an arch but is a 580 foot was a suspension bridge. With the design of the Craigellachie, Telford noticed that he made,

what he would call, essentially a mistake, and he corrected this with the Mythe Bridge.

Mythee Bridge,  source: Google picture

If we look at these two bridges we see that the landscape is different

so you might notice they are different bridges by the landscape.

But if you look at just the bridge itself, can you notice the difference

between the two bridges? Because they are very similar to one another.

The difference between the Craigellachie Bridge and the Mythe Bridge is in the spandrels.

It's in those diagonal members that connect the deck to the arch.

If you look closely at those diagonal members you'll see that they're oriented differently

in the Craigellachie versus the Mythe.

In the Craigellachie, if you take the bisector of those diagonal pieces you'll see

that bisector is normal to the arch.

It's coming perpendicular to the arch.

Whereas in the Mythe Bridge the bisector of those diagonals is vertical.

It's completely straight up and down.

In the Mythe Bridge, this is a more efficient way of carrying the loads.

The loads in those diagonals are more efficiently or more evenly distributed

between those diagonal members, whereas in the Craigellachie Bridge

in particular, those diagonals that are leaning or more horizontal are carrying much less load

then the diagonals that are more vertical.

Now we come to the Menai Bridge completed in 1826,

a 580-foot span suspension bridge designed by Thomas Telford.

Now there was a need to design this bridge and the need arose from the active union of 1800

which merged the Kingdom of Ireland with the Kingdom of Great Britain.

They needed to connect London to Dublin and to do that you had to go through the Island

of Anglesey all the way to the tip of Holyhead.

And to get to Holyhead and even Anglesey you had to cross the Menai Straits.

If you look at the side spans of this bridge we see that it has both arches and suspenders.

And this again is ambiguous.

It doesn't tell you clearly how those loads are being carried.

But Telford did this because he was concerned about the wind.

He wanted to make sure the back stands were heavy and anchored.

Just before the bridge opened, Telford's resident engineer noticed undulations

from gusting winds so Telford added bracing, which cut down the movement.

Ten years later, about two years after Telford's death,

the bridge keeper reported large oscillations and unfortunately no action was taken

and in 1839 a gale tore part of the roadway loose.

Telford's writings in the 1820s and his resident engineer's field observations showed how

horizontal wind can cause extensive vertical motion in a suspension bridge.

Unfortunately, this lesson in history was lost in the bridge designs to come, as we will see.

In the Menai Bridge, although the towers look heavy, they're actually hollow,

like in the Pontcysyllte Aqueduct Bridge.

So Telford again is thinking about efficiency in his designs.

Let's use the Menai Bridge to define some terms for you as related to suspension bridges.

The first term that we have to understand is span.

When we talk about a span of a bridge we're talking about the longest unsupported length

and for suspension bridges, that distance is from one tower to the next.

Next, let's look at the cable.

The cable goes from anchor to tower, to the next tower, to the next anchor, and it is in tension.

And it's in tension due to the uniform loads imposed by the hanging suspenders.

The suspenders are the vertical elements that suspend, or support, the deck.

The form of that cable is parabolic.

I'm going to do a brief demonstration for you to show you the shape that these cables take

when loaded and it will give you a better sense for why the form

of a suspension bridge cable is parabolic.

In this demonstration, this chain represents the cable of a suspension bridge.

We know that the chain can only take tinsel forces.

It can't take any compression forces.

It could be stretched but it can't be squeezed.

So let's look at how the shape of this chain changes when we add loads.

So if I add one load right in the center we see the V shape that this chain takes.

But if I— Now, I'm going to add continuously load along this whole chain,

we're going to see it start to take the form of the cable

of a suspension bridge, which is a parabolic form.

Now you start to see the shape change a little bit more…

and more. So these weights represent essentially the load that's transferred from the suspender,

which is the vertical elements of a suspension bridge, to the cable.

And it's the load represented by the weight of the deck.

And we see that as I add more and more of these loads along the chain, we're starting to see

that parabolic form takes shape, which is the shape of the cable in a suspension bridge.

Telford designed his bridges for carriage loads but the railroad age was approaching

and that is where we move to next.

See you in the next Section guys :).

Cahaya Tauhid#1

A lonely drive went to home this evening, I was heard a 92.30 Mhz frequency Radio ( I forgot the name),

He was Aa' Gym shared about How Prophet Muhaammad SAW keeps his words. He never speak something that unnecessary, so he merely to say something. But, in case when He said something, those sentences shoud be going into thousand miles away pinetrating our soul. So deep and meaningful. His word it was like a root that absorbed nutrient from soil that make the tree fertil. But everyone know that root was underground.

That was figure of our Prophet Muhammad SAW, he provide our tauhid its like a root. Its underground but can make a very tough tree and beautiful flower

Yes, kakak kamu pasti bisa, ada Allah yang lbj dekat dari nadi, yang maha sami'un. Semangat mbak nourma :))

Kapan aku terakhir uninstal ig, maret 2017 sampai september 2018. Lumayan lama.

Detoks dari racun2 sampah yang mengotori jiwa. Sayangi dirimu sendiri. Jangan berharap sama manusia, berharaplah pada sang pencipta, manusia itu fana, Allah kekal selamanya

Dunia itu tempat cari bekal sebaik baiknya, bekal kebaikan yang kelak membuat Allah ridho, so sekarang ridho dulu terhadap segala ketentuan Allah

Jalani takdirmu berusaha sekeras dan secerdas mu, berdoa, lalukan maksimal hasilnya serahkan pada Allah.

Semangat nourma

Di umur sekarang saya sadar, hal terbaik yang saya lakukan adalah berhenti memberi tahu orang-orang atas apa yang terjadi dalam hidup saya. Setelah bertemu banyak orang, saya mulai mengerti bahwa menjaga privasi adalah hal yang sangat berarti
