**English - Ms. Sue**

Ms. Sue having loads of trouble here could you please help me? Actually Mohammad and I just went on the site Animoto and it won't let us put full sentences. Maximum letter count is 30. Exactly how do I shorten this sentence? Jake draws himself away from everyone and thinks...

Could you also please delete this post. Don't want others to copy and paste my work.

Thanks Ms. Sue you know what title I could use for one of these images?

**English - Ms. Sue**

Like Mohammad, I'm going from darkness to lightness so I'm not sure what image to add for the second slide. Is there something that represents a mood in which you feel lonely and can't express your feelings?

**English - Ms. Sue**

Thanks so much Ms. Sue can you suggest me a title I can use for this presentation? I'd like to add a header for my second slide.

**English - Ms. Sue**

Thanks very much Ms. Sue =D

Thanks so much Ms. Sue I will definitely add that to my essay which I'm working on. So then the theme would be --Take positive action and look ahead-- And nice to meet you Ms. Sue :) I will post my essay as soon as I'm finished writing it, and if you could also drop it...

A force F = 7^i + 6^j - 5^k lb. acts at the origin. Find the magnitude and direction cosines of the moment of this force about point A (-4; 5; 6) ft So in this case wouldn't vector r= -4i +5j +6k and vector F = 7i + 6j - 5k lb? and r X F = -61i +22j -59k = MA [MA]= 87.67 ...

A force of 26 lb. acts through a point (4; 5; -7) ft. and is equally inclined to the positive ends of the orthogonal axes. What is the moment of this force about the origin So i'm assuming vector r is 4i+5j-7k? And using the fact that cos^2α + cos^2β + cos^2γ...

**Engineering**

Such as (2i-7k+2k) + (-2i-6j+26k)? To get to get my final vector in which I take the squareroot of the sum of the squares? Also thanks I didn't recognize my conceptual error. But I still believe it would be M1 + M2.

**Engineering**

Thank you, I reevaluated my work and found all the errors. Though I'm not sure sure why you would subtract M1 and M2 if you are looking for the total force applied? Wouldn't M1 + M2 make more sense in this case?
