Making an ENGINEER think OUTSIDE THE BOX in Poly Bridge 2!

So we're at the point where I'm having to think outside the box in Poly Bridge 2. The levels are becoming more difficult, and I'm having to adapt to concepts outside of engineering reality to find solutions that work. This week we take on the triple decker drawbridge, the safety gap and the big spender.
This video contains solutions to levels 4-5, 4-6 and 4-7.

A gappy bridge sure wouldn't be allowed in real life, but it was a lot of fun learning a potential new way to shave cost in this game! Which level did you guys enjoy most this in this episode?

[@StarfoxHUN]

But isnt every wooden road bridge is a gappy bridge?

[@alvargd6771]

My favourite one was the first one Also in the second bridge there was a lot of dangling bridge potential. you could use smol springs instead of wood between the roads and have it just dangle with his springs holding it

[@MrGreg242]

Those curve-y curves are some BILFs. They got the looks and decreases your cost which I know engineers love doing. Keep up the vids.

Sebastian I love that bridge, was fortunate enough to see it as I convinced the missus to take a detour whilst we were on holiday earlier in the year!

I must say, i really like how you edit your videos and also the fact that you integrate your job into them. As you like Poly Bridge and Engineer Games i suggest that you might like Factorio, just a suggestion though, i'm not forcing you to anything, i just think that you would like it. Also, stay like you are and good luck in these... strange times.

[@JETZcorp]

Having never played the game, I was not expecting you to get away with clipping big sections of roadway together to make a drawbridge. I guess it's all about load support so Ghost Pavement is not a concern.

"I know safety. I'm an engineeeeer!" ..A few moments later.. 10:57 "Ok, so this is going to be a bit of carnage."

lol yeah, what he really means is "I know how to make things more dangerous".

[@swine13]

He said he _knows_ safety. Not that he insists on it. 😉

[@zinsch5588]

On the triple decker level, I made the top road arch above the ship. So the two ends of the bridge always stayed connected, making it easier to hold everything up. And I built a little hurdle for the middle car, so it will be delayed and only two cars are on the bridge at the same time.

[@RealCivilEngineerGaming]

Sneaky

[@F14thunderhawk]

@@RealCivilEngineerGaming Also when youre using multi-deck parallel bridges, at least in the simulation you want to anchor the bridge anchors directly to eachother, top to bottom, not Truss Intersect to Truss intersect. Doing so increases the structure's rigidity, which is not the case when doing a horizontal support.

[@doylemichael]

you are my new favourite channel. I love how real you are in your q&a videos, you made me feel a lot more at ease with uni. it's taking a bit longer than I planned but as long as I finish right?

[@NoodleNut81]

It's called game logic

[@harrisredpath]

Sanguine means blood, as in Blood Gulch. Pronounced 'San-Gwin'. Love the vids, keep it up!

[@jonny822]

it also means optimistic or positive, especially in an apparently bad or difficult situation according to google. provokes the thought: which meaning did polybridge mean? 🤔

[@harrisredpath]

@@jonny822 I just assumed it was a reference to Halo, but that might be a more uplifting meaning

[@IanBPPK]

@@jonny822 yes

[@connor0959]

Harris Redpath I thought that same thing

[@RealCivilEngineerGaming]

It was a reference to halo btw, the producer commented on another video of mine pleased that someone got the reference!

[@kasuraga]

8:00 I think the extra lanes act as a counter weight so the whole thing can pivot smoothly without breaking

[@royalRoy5]

8:00 I'd say it's build symetrically like that, so it has the instantaneous center of rotation and the center of mass aligned in the same point and therefore negating the aditional stress on the bearing it would have gotten due to the inbalanced rotation. Though of course, this leads to doubeling the stress caused by gravity on the bearing. Sooo I'm not sure wheter this trade off is worth it or not ^^

[@groundedgaming]

🤓 but that's a nice way of saying, for balance.

[@TPLJakub]

Everything fell apart on the first bridge because that bottom joint wasn't attaching, I'd recommend always keeping hydraulics at max (50) and only changing the position of the joint it's attached to.

[@legionnaire5947]

5:09 “Oh, bollocks!” made me heartily LOL XD

[@beeble2003]

8:00 "Why has it got the three extra lanes on top?" Counterweight. The moving part rotates about its centre of mass, so the static stress on its support doesn't change when it turns.

[@connorgregory3986]

The one where you asked about the 3 on top, it was a counter weight to allow to the motion to actually work with the hydraulics and made it so it wasn’t just a pendulum on one point creating immense forces

Triple decker drawbridge, just when everything is going great, life finds a way to drop three of your cars into the abyss.

[@M3dicayne]

The first bridge kinda breaks the laws of physics. I haven't heard of any solid material travelling through other solid material without problems at the speed of a slow driving car without causing cold-deformation. This is - however - pretty much what the title says... Thinking "outside the box"....

[@WingmanSR]

Yes, can you just imagine; inputting a word with some type of letter-selecting device, into a separate electronic device, then being presented with a multitude of sources for definitions and pronunciations, even in different accents? That is truly the future, my friend! 🤓🤯

[@paulypoobrain2929]

SBwingman wait! Isn’t that a thing. You type out the word on a type writer, give the word over to be sent telegram, the telegram reaches the pony express they ride out to the professor and all his books, the professor researches the word, types up the information, gets the local pony express to take it to get telegraphed and then sent to in inquirer. All in a matter of weeks. So fast! Technology 🤯 amirite.

[@swine13]

Have you ever heard of a game called Armadillo Run? I think it would be perfect for your channel - its a physics based game where you need to get an armadillo into a portal using various materials with different costs and tensile strengths. So you can do things like create slingshots, rubber catapults, anything you can think of as long as you stick to the budget and the armadillo stays in the right place for 5 sec or so. Old game, but brilliant. Highly recommended

[@benruss4130]

I think that arched roads help a lot more with cost than you think. While both of us know that the arched roads are generally a no-no, they allow a more even split of the load between the trusses and the road, which allows MUCH tighter tolerances. Instead of fighting forces with a moment arm, you run the forces along a straight line.

Loving the content rce! I hope you follow through on some of the challenge levels because they really put one’s building skills to the test. You might want to consider doing challenge levels before world 5, world 5 is much much harder than the previous worlds and even most of the challenge worlds 1-4. Also would you consider turning the audio level down for your outro song? It’s just a little jarring in my opinion. Keep up the fantastic work!!

It's pronounced like sane-gwen. Also when referring to a gulch it typically refers to the definition of blood-red, but this case seems to be a bit of a pun. 1. optimistic or positive, especially in an apparently bad or difficult situation. "he is sanguine about prospects for the global economy" 2. LITERARY•HERALDRY blood-red.

Would've been cool if you made all 3 roads in the first level move in parallel to one another but all connected to the end of their roads, using one short hydraulic connected to pull all 3 up in a manner akin to a pantograph linkage. It probably won't work, but food for thought.

[@hopguy666]

Difference between engineering degrees. Industrial engineers build a bridge that works perfectly but they have no idea why. Civil engineers build a bridge that collapses and they know exactly why.

[@tarrantwolf]

It'd have been cool if there was a slider piece, a beam that couldn't pass through other pieces of the same type of beam. With that you could have made something like a bridge that could extend horizontally.
