### Young’s Modulus on the TI-89: Video Transcript

This video is on young’s modulus with regard to physics classes and uhm let’s get started here you’re gonna press second alpha put in the letters p h y s i c s.
Press alpha again to put in the open and closed parenthesis.
Press enter and you’re into my physics menu you have many choices here for you to pass physics.
If you’re like me you’re not interested in learning about physics you’re interested in passing physics from tests.
When I go on the internet to check these it takes me an hour to find anybody that does actual examples of with numbers to show you what to do.
But my programs are all designed for passing tests and getting homework done
Anyways you can go all the way up to the top and since young is a y you can go down to the bottom of the alphebet and come to youngs modulus.
Press enter and you are into ah you have to find stress first and you have to find strain because
youngs modulus is stress over strain and here’s what you put down on your paper.
For stress this insignia here equals force over area so we do that also any calculations in the entry lines of my programs.
Press alpha we’ll put eight and either grams miligrams or kilograms let’s say it’s and also I ask you sometimes they give you diameter sometimes radius sometimes cross sectional area.
I’m just going to do diameter right now and we’re going to put alpha point seven maybe centimeters.
I change it for you so you have the exact conversion rate and here’s the stress for that two pascals
and you put all these calculations down on your paper.
Here’s the formula here and pi r squared is the diameter or area and we need to find strain.
They’ll give you the stretch and the length of the cable or string and so let’s put the stretch alpha maybe point seven.
Let’s say it’s meters and the length let’s say that that was alpha nine meters I always show you what you’ve entered.
So you can change it if you want If you’ve made a mistake on the calculations or entries so strain turns out to be
that formula and then answer and young’s modulus then turns out to be this that you write this on your paper two point six two etcetera M n per meter squared.
uhm pretty neat huh EveryStepPhysics.com
Go to my site buy my programs and pass physics.

## TI-89 Titanium Physics Program Example

### Young’s Modulus Example on the TI-89: Video Transcript

This is a video from every step physics dot com
solving a physics problem step by step and also demonstrating how my downloadable
programs work in your TI 89 Titanium calculator and other TI calculators
for calculus and physics problems andlet’s get started
to access my physics menu in my programs you goona have to press second alpha
and put the letters p h y s i c s in here and then press alpha and put
the open and closed parenthesis press enter and you’re into my menu
you can see how many things there are many many things here
you I have that outlined in my outline that you can receive
but uhm we’re going demonstrate tension right now
so I’m gonna go up here get to the t’s
It’s all alphebetical and click on that
and you have all these choices here what they give you
what happens in a physics test is they give find acceleration
this is a video from every step physics dot com
demonstrating how my programs work with the t i eighty nine titanium calculator
and other calculators in the t i system for physics and calculus problems
This is a t i eighty nine physics program and let’s get started
your going to push second alpha to put in the letters p h y s i c s
the press alpha to put the open and closed parenthesis
press enter to get to my menu many choices here
you can scroll up to get to the bottom of it
there’s young’s modulus and work given different ah parameters
ya know it’ll say in your test it’ll say what work is done by
this object or something like that and then they give you these
parameters and you have to scroll to find what they give you
choose that one and you’re homework is easier and you can
pass your test quickly uhm let’s do work across the floor
wait for the program to load here this is box accelerated across
the floor find net work given
mass, acceleration, and time you have to press alpha before
you enter anything into the entry lines here.
press alpha the mass is eight kilograms
acceleration, alpha twelve and the time alpha five seconds
I show you what you’ve entered so you can change it in case you made
a mistake press one it’s ok
and here’s the net work the formula and everything
you write this on your paper within one minute you have exactly
the correct answer and you can go on to the next problem
pretty neat huh every step physics dot com
