This video also covers a concept called variables that allows us to store data so that we can use them later in our program. Here, we will learn to print variables and give good variable names so that our code is easier to understand.

Shell Scripting Tutorial for Beginners 24 - Local variables

C1C2
11 Pogledi · 4 mjeseca prije

LOCAL VARIABLES IN FUNCTIONS :
Variables defined within functions are global, i.e. their values are known throughout the entire shell program keyword “local” inside a function definition makes referenced variables “local” to that function. Local variables can be created by using the keyword local.

Understanding Vibration and Resonance | RockTV

C1C2
10 Pogledi · 10 dana prije

Watch the companion video on RockTV here: https://rocktv.app/

In this video we take a look at how vibrating systems can be modelled, starting with the lumped parameter approach and single degree of freedom models. We then go on to look at damping, the dissipation of energy that occurs in all real systems, as well as forced vibration, resonance and multiple degree of freedom models.

ERRATA:
- At 04:16, the terms sqrt(k/m) appears not in the equation of motion, but in the *solution* to the equation of motion

For further reading I'd recommend the following:

Lyrics:

When I need space that’s where I go
A place to escape that nobody knows
Where I feel free to let things go
And face this evil that burdens my soul
I bring my hatred, I pack my pain
All the emotions I cannot explain
It’s where I found God
And filled that whole
It’s he, myself and I
On that lonely dirt road

I needed somewhere to take my mistakes
I didn’t want my family to see me cry
They’ll never know I’m
carrying all of this weight
Dealing with the pressure
of trying to provide
No sign of struggle can show on my face
They ask if I’m OK I just flash them a smile
Fire up that engine to take me away
I’m speeding through emotions with every mile
On that road is where I find my peace
I remember daddy told me about some times like these
On that road is where my minds at ease
I keep driving life away, rejecting change so

When I need space that’s where I go
A place to escape that nobody knows
Where I feel free to let things go
And face this evil that burdens my soul
I bring my hatred, I pack my pain
All the emotions I cannot explain
It’s where I found God
And filled that whole
It’s he, myself and I
On that lonely dirt road

I tried my best to plant the seeds
And then I watered everything that was in my life
But as a man, the only flowers that you get
Are when you’re 6 feet under on the day you die
I think I feel the pain my father felt
It’s finally sinking in
looking back all I see is his eyes
He said that house is not a home
Unless you build it on respect
with some kids and a loving wife
If these walls could talk
I bet they’d say it’s all my fault
That I don’t try hard
That I ain’t man enough
That I ain’t standing up
That I just burn everything
that my hands touch
If these walls could talk
I bet they’d say I’m to blame
That I’m the one who put myself inside of all of these chains
That my addictive personalities what ran them away
And that I hurt myself by staying quiet
And not explaining I’m broken
In places, I can’t even see
I know there’s gotta be a heaven
Because the hell that’s in me
Is taking a dangerous toll
That I’m paying with all of my soul

When I need space that’s where I go
A place to escape that nobody knows
Where I feel free to let things go
And face this evil that burdens my soul
I bring my hatred I pack my pain
All the emotions I cannot explain
It’s where I found God
And filled that whole
It’s he, myself and I
On that lonely dirt road
