Mechanical Vibrations #1
Oscillatory motion
Systems come in 2 flavors, free vibration and forced vibration.
Free vibration: The thing is left on its own to vibrate
Forced vibration: It's being forced to vibrate like by a motor or pushing it
The number of variables needed to fully describe the position of the system will be useful later on, but it's pretty simple. Mentally jiggly a part of the system and see how many unique directions it's allowed to move in without effecting other directions. Typically, if it moves in straight lines, X, Y, and/or Z is most useful. If it rotates, polar coordinates are most useful where it's measured as an angle, and a radius from the center of rotation
Fantastic, we now know the types of wiggling and that things move in a combination of unique directions. Now lets trace the path of something vibrating. Look at that wave. As per the standard sine wave junk, we can adjust how fast it rotates by multiplying the thing in the sin function (omega), adjust when it starts by adding to the thing in the sin function (psi), and adjust the height by multiplying the whole thing (A). Though to be honest, we're hardly if ever going to need psi (it'll basically always be equal to 0. That makes things easier)
From here, the book I'm going off babbles on few pages talking about complex conjugates, Fourier series, RMS, and decibels, but I'll be honest, we don't care about that rn. If they become useful, I'll talk about them, but for now these are the tools we need to move on.
Post credits scene
So, this series of posts is meant to help me learn more about the subject. Aptly named "This is not for you", it's for me. I'm more than happy to read or reply to comments and questions, but at heart, I need to fully understand this, and this will hopefully achieve that. If I make a mistake, correct me. If it feels like these posts get more and more incomprehensible, and the art style constantly shifts, this is why.
Thank you for reading

So I've read pink ice about 17 times now and i love you're writing and like desperately need like heart shattering soul crushing wilford angst like maybe wilford having an episode and accidentally shoots and kills reader?
Let’s celebrate my first official ask with some trauma ;)
Trigger Warning: Major Character Death, Suicidal Themes
Was It My Fault?
Wilford Warfstache x Reader
He held the gun, the well worn metal pieces clinking softly as his hand shook.
It clicked as he spun the chamber, and he stared, transfixed, at the rotating metal. When it came to a stop, he held it up to his head and pulled the trigger.
The hammer struck with a hollow click. Another empty.
So far, this game of roulette was proving rather boring.
If anyone had been in the room in that moment, the maddened look in his eyes would have sent shivers down their spine.
His grin seemed stretched too wide, his hair was messy and falling over his cold, empty brown eyes.
He spun the chamber again, and pressed the cool metal barrel to his temple. He felt his heart race, a feeling that was lost to him most times. The coolness was comforting. Like an old friend.
And old friend….
Suddenly, there came a soft knock on the door. The sound was enough to snap Wilford out of his stupor. The life returned to his eyes, and he sat up a little straighter. You must have come home.
He shoved the gun under the pillow of his bed and ran a hand through his untidy pink hair to straighten it.
He went over to the heavy manor door and pulled it open, barely giving you time to say hello before he drew you into a backbreaking hug.
“Mmf-! Hello, Wil.”
You smiled and hugged the broad-chested man back the best you could from your place in his arms. Wilford, when it came to your relationship, was clingy and very, very sweet. Almost like cotton candy.
Though you knew how dangerous he could really be. You were confident, however, that he would never hurt you.
Finally, the bubbly man let you go, his smile turning up the corners of his pink mustache. Though your feet were back on the ground, his arms never left your waist.
“Hello, gumdrop!” He chattered excitedly. “You’re finally home!”
You laughed slightly. “Yes, Wil, I’m home.”
He leaned down and gave you a long kiss, which you accepted gladly. He tasted sweet, like bubblegum.
He grabbed your hand and pulled you back into the room, closing the door behind him, never breaking the kiss.
He loved you, there was no doubt about that to him. More, he thought, than he had loved Celine. Though his heart suddenly ached at the thought of her, it was quickly dispelled by the feeling of you against him. You were the only other thing since the… accident that could make his heart race. That and his trusty pistol.
You gently pulled back from the kiss to catch your breath, laughing quietly. Wilford often forgot that you were mortal, and needed to breathe.
He responded with a low chuckle, and buried his face into your shoulder. His mustache tickled your skin, and you laughed, trying to push him off you.
Sensing your efforts, he simply went limp. The sudden weight on you made you collapse backwards onto the bed, with him on top of you. You laughed more, and he shot you a wide grin.
“Falling for me already?”
“Shut up,” you huffed, then shifted to sit up. As you did, however, the pillow moved from its place. You stiffened as you caught sight of the gun’s handle, and the mood quickly darkened.
You looked back and Wil, stern with narrowed eyes. “…You’ve been playing roulette again.”
Before he could answer, you grabbed the gun and rolled out from under him, dashing to the other side of the room.
He looked at you with worried eyes, his brain beginning to fog. With the gun out of his hands, and old memory began to surface.
“Worthless,” Celine said, holding his gun and staring at him with angry eyes. “Absolutely worthless. You were supposed to be with Mark, and instead you’re out hunting…”
She tossed the weapon to one side, and he winced at the clattering sound it made against the solid oak floor. “I could have been found out! My marriage, my position, my status… I thought you cared about me! You almost ruined me!”
It was always ‘me’. Never ‘us’. Never ‘we’.
Always about her.
He felt the anger start to build. Celine had ruined him, taken his brothers’ trust from him, made him out to be the bad guy…
And as he looked back at you, he didn’t see you at all.
He saw Celine.
Celine stood in front of him, her veil over her eyes and his gun in her hand. Rage flared up inside of him.
“Bitch,” he sneered. “You took everything from me.”
You tensed slightly at the tone, the word stinging a bit. You decided to ignore it and try to calm him down.
“Wilford… take a deep breath…”
“Don’t tell me what to do!” He snapped, striding closer to you, his fists balled in anger. “Everything would have been fine if I’d never gotten involved with you and your freeloading!”
You felt tears start to prick your eyes. You didn’t understand, everything a second ago had seemed just fine.
As he got closer, you tried to stand up straighter, to look stern.
He leaned closer to you and tried hard not to flinch. His tone was dripping with malice as he spoke again.
“I fucking hate you.”
You had tears running down your face now. You didn’t even flinch as Wilford grabbed the gun from your hand and pointed it at you.
There was the sound of gunfire, and everything went dark.
Wilford watched you fall, blood pooling from the hole in your chest. But something was off…
It wasn’t Celine who fell, it was you.
His eyes widened, and he caught you before you fell, getting soaking his shirt in blood, the crimson standing out against the pink.
“No…. No, gumdrop, please…. Please.”
You didn’t respond.
He snapped then.
Everything faded together. He clung to you, soaked in your blood. He stared at your glassy eyes for a moment before he started to laugh, tears streaming down his own face.
“Ah, cupcake… you always knew how to play a good joke. Heh… Cmon, sweetheart… wake up, you got me.”
He held you until you turned cold, his sobbing laughs echoing through the manor.
