Statics: Using Double Projection method to break a 3D vector into xyz components

Walks you through how to break a 3D vector down into it's x,y, and z comp using the "Double Projection" method.
Make sure at the end, you manually put the correct signs on your components. In this case, I forgot that the y component is pointing in the negative y direction, and thus should be a negative "j-hat" component
Note that the equation "A=..." is the general equation for double projection. Do not associate it with the example problem above it

First video that genuinely helped me understand this. Thank you so much!

[@catherineblandon6021]

Thank you so much I have been stuck on this for a while. What a relief!

[@eng1048]

Glad it helped!

LIFE SAVER, THANK YOU!

[@tristenwhite1174]

Much appreciated, thank you!

[@eng1048]

You're welcome!

[@talhajat3301]

holy fuck I finally got it

[@eng1048]

excellent. bro fist dat shit

[@WillTheRex]

Thanks man this helped a lot

[@WillTheRex]

However wouldn’t the y component be negative? Since it’s direction is opposite of the pos y axis

see the video description

Thankss mate you solved my problem

[@eng1048]

Bloody hell no problem lad

[@userutoob7]

In the formula that starts "A = " shouldn't the coefficient of the k unit vector be sin phi (instead of cos phi)?

[@eng1048]

That equation is snipped from the textbook, the figure that it describes is not shown in the video. Do not associate the equation with the figure above it. Thanks for spotting that!

sorry to necro but im pretty sure the j component is supposed to be -44.5, other wise great vid and i agree with you 100%, no reason to memorize that formula

[@eng1048]

yeppers looks like i've already got a note about that one in the vid description (it's where i put all the corrections for my vids) Thanks tho my guy!

[@beatboxersleepingman]

thanks for this!

[@eng1048]

No problem :)
