AI Thread Summary
To find the resultant vector graphically, move the starting point of vector E to the tip of vector F and draw a line from the origin of F to the tip of E, which represents the resultant vector. This method creates a triangle, where the sides represent the original vectors and the resultant is the line drawn. To determine the lengths of the vectors, use a ruler to measure them proportionally, ensuring to maintain scale. For example, if F is 80N and measures 8cm, the scale is 10N/cm, allowing for calculation of the resultant force. This graphical approach can also be applied to more complex shapes like squares by following the same principles.

I would show work, but I am not sure how to even approach this, please help! Thank you!

Move the point at which the e vector begins and put it at the end of the arrow of the F vector. Draw a line from the point the F vector begins to the end of the arrow on the E vector. Put a nice little Arrow at the end of the line you just drew by the end of the E vector, and that is your resultant vector. Make sense?

edit: your vectors will kinda look like this: _/, where F is the flat vector and E is the /. Your resultant will be the line that goes from the origin of both vectors in the beginning, and end at the tip of the moved E vector.

no. Excuse the crude use of mspaint.
It'll look like:

technically you don't need the Left E vector and top F vector. You see how I just moved the E vector over to the F vector? and drew the resultant from beginning to E's tip.
 
ohh! I remember learning this in trig last year!
but, how do i do this when I don't know how long each side is?
 
Graphically. Use a ruler and find out how long they are. Graphical method is proportionate.
 
so if i have 9.5 & 5.5 how do i find the resultant? I completely forgot over this summer
 
draw it all out, and measure the resultant. the distance you measured is the resultant. ie, if F=80n and it's 8cm long, that's 10n/cm. You draw it all out to scale, measure the resultant. and 10n/cm*R= Resultant force.

what if its more of a square? like this

do you make it into a square and draw the resultant and measure?
You draw the resultant just as you were shown in Post #4 earlier. And yes, then you would measure the resultant.
