Find the Resultant Force using the Parallelogram Method

[@sleepless8823]

I've got to work on my report on Gravesand's apparatus which requires parallelogram method to find the resultant force and this vid really helps me out. Online classes are so tedius, Thanks a lot .

[@josedou6312]

Thank you, that was what I needed in my first lecture of vectors in a mechanical engineering book.

[@MathandStatsHelp]

You're welcome. Glad it was what you were looking for

[@juanahjjo6685]

You're the best you just helped me with a problem I battled with for a year now thank you👏❤

[@eliotlaurent3278]

very straightforward and efficient. thanks

[@mikailmirzasafdar6803]

Nice video. How would one go about finding the direction of this resultant force?

[@Zhinoi]

To think my geometry teacher said I wouldn't need to remember triangle theorems... Well here I am in statics 😅. Great explanation!

[@johnkupa8885]

how do you find the direction of the the resultant force that you've found??

[@laibahamid8233]

Same question

[@adeoyeaire9076]

Straight to the point. Please can you break down the pallelogram law ,🙌🙌

[@HaswelMakolija]

Thanks for your good explanation

[@shinelikeadiamond9935]

How to do it without using cosine rule ??

[@heshmaniyaz8069]

Draw a scale diagram, and measure the diagonal using a ruler, and convert it to the force unit using the scale eg 1cm:2N

[@oduromaxwell]

you are really the best ...very understandable.

[@MathandStatsHelp]

Glad you found it understandable!

[@FenetAbilu]

When we use negative and positive in the formula?

[@james9531]

if the degrees are difffrent can you still use the same formla to find the

[@dancinglikecrazy5510]

THANKKKKK YOUUUU I was soo lost you had no idea lmao

[@diamond6162]

That was awesome but can you do one on how to also find the angel of the new Force

[@shelbyoxenford3426]

Very thorough! Thanks bunches!!!

[@ab_obada5012]

You found only R force but where is the direction ?

[@crappycapybaras]

this really helps me a lot 😭😭 I hope I won’t fail my physics test tmr😩🤦‍♀️

[@MathandStatsHelp]

I'm glad it helped you. I wish you the best on your test!

[@reginat177]

Why can't my professor explain it this way. Totally understood it

[@tahseensaad7860]

what is the existence of(2) in ( 2abcos135)? is it because we have 2 forces or is there some point behind it? please if you could explain why the law is like that?

[@MathandStatsHelp]

It has to do with the derivation of the Law of Cosines. The Pythagorean Theorem, a^2+b^2=c^2, only applies to right triangles. The Law of Cosines applies to all triangles and is derived using two right triangles within the given non-right triangle. You can Google derivation of Law of Cosines to see how it is derived. It's very hard to type out the process in a reply.

[@somebye2992]

Can u pls make a video how can u draw a parallelogram when both arrows oppositely

[@somebye2992]

For instance when the arrow is pointing from C to A

[@Cathyjanes]

thank you so much. this was so helpful

[@scored3003]

Thank you so much this really means a lot

[@MathandStatsHelp]

You're welcome. I always like to hear I am helping people!

[@rubentuting525]

how about the location theta?

[@sirpanda5280]

how did you get the calculator on your computer?

[@MathandStatsHelp]

It's the teacher software that I use that I got from Texas instruments. I think they make a student version too, but I'm not sure.

[@InguagRowak]

Could u show me how u put calculate in degree mode

[@MathandStatsHelp]

It depends on the calculator. They all have different methods.

[@cipherbenchmarks]

how do you virtualize the ti-84 like that

[@MathandStatsHelp]

It's the teacher software from TI-84.

[@jeremiahopadeji6629]

Very nice

[@bosej.aikore5930]

Please, if you want to find the resultant of the force along AC in the diagram?

[@MathandStatsHelp]

What other information are you given?

[@FarahNajey]

Great❤❤

[@sharoonaftab8894]

I don't understand how the angle c is 180-45? Please help with this.

[@MathandStatsHelp]

Since the opposite sides of parallelograms are parallel, the rules for parallel lines apply. The two angles are same side interior angles and they are always supplementary. Supplementary means they have a sum of 180°.

[@sharoonaftab8894]

@@MathandStatsHelp thanks ! That does ring a bell from the geometry class

[@loidendapewa]

Thanks for making me understand

[@MathandStatsHelp]

You're welcome.

[@sukarlynnenamo5870]

Thanks Alot....🙏🙏🙏🙏🙏🙏

[@keishanimi2654]

Thanks loads

[@rejopra6818]

Thank you

[@kyanzuniga9721]

THANK YOUUUU!!

[@MathandStatsHelp]

You're welcome

[@discordequalpunk]

how to find this without angles?

[@MathandStatsHelp]

I would need more information as to what you are given to be able to help.

[@bryansanqui8982]

The best

[@jhonahronbunye6424]

Kulang po!! Nasaan na 'yong s apangatlong quadrant

[@nathanielloquinario2104]

Thank you 😊😊

[@MathandStatsHelp]

You're welcome!

[@AnzzCheatedOnMarkWithHaechan]

Tyssm 💗💗

[@ambelasistin732]

To get the angle of c, why 180°?

[@MathandStatsHelp]

Since it forms a parallelogram, the consecutive interior angles (angles next to each other) are supplementary.

[@ambelasistin732]

Thank you very muchhhh

[@wacaalbulsho]

Can I get that calculator app

[@MathandStatsHelp]

It's the teacher software. I know TI has a student version, but not sure how expensive it is.

[@donkordavidtetteh116]

I have more explanation on how you get the angle for the cos

[@khuziwe.sithole3079]

THAAANNNKKK YYYOOOUUUU!!!!!

[@bababaykaa9613]

Great;)

[@mattjackson4177]

Why can’t you just measure the length of c

[@MathandStatsHelp]

It's not drawn to scale. Sometimes you have things that can't be measured directly, which is why we use Law of Sines and Cosines to help with measuring things indirectly.

[@mattjackson4177]

Math and Stats Help Ah thanks, helps a lot
