Dude!!!!!!!!!! I was hopeless in Mechanics, now I feel way more confident. Thank you.

[@1963rzr]

You are welcome dude!!!!!!!!!

So i just got done with midterm and the first thing i am gonna do is write this comment, You are the reason i did it so well, Your voice and these videos ran like adrenaline through my veins during the exam as i rushed through it massacring every damn question , i dont know to thank you and i will never forget you

[@1963rzr]

Thank you. Hope you did very good.

I have my first exam coming up soon and this video just saved me and let me understand the material so much better. Thank you so much.

[@ZainKhan-xx6np]

i have my exams coming up and i am lucky to find this video thanks man for such a good i hope our teacher would teach us the way you do. Thanks a lot man.

You are welcome!

[@aboraba71]

such a great lecture. Thank you soo much. I actually passed my exam related to this chapters with an A, thanks to you.

[@1963rzr]

thank you. glad it helped

+STATICS THE EASY WAY. should I place or put an arrow over the letter when i'm expressing a magnitude?

[@1963rzr]

+Abo Raba I really don't care. however it is not correct. arrows are use for vectors unless you also use the two vertical lines before and after for magnitude. remember to like the videos. ..

+STATICS THE EASY WAY. oh okay, thank you again. you are a great doctor. sure I liked the video and i'm going to sub to your channel 👍

Good day, sir. May I ask how did you solve the last equation in 1:05:01 where you multiply the top equation with 1.5? How did the 3/7 become 4.5? How did you get the forces?

[@1963rzr]

Hi, Good day to you too. Multiply the top by 1.5m and add the two equations. -3/7 becomes -4.5/7 and add -2/7 then you have 6.5/7AC=500 ; hence the AC=538.5 This is just solving systems of equations. Please review your math concepts. Good Luck, Stay Safe

@@1963rzr I understand how you get the force in AC but how did you get the force in AB?

thanks a lot that was very helpful to understand to solving problems.

good day sir, having all the forces in the rope, how can I compute the maximum weight of the object?

[@1963rzr]

just do summation of forces in y for that particle

Hello, for the problems of the springs in the time 50:26, I do not get how did you came up with 7/5AB if before you put 4/5AB. I did it different but got the same answer. I am just wondering how did you do it.

[@ncamilung2640]

Hi Sir can I have a website where you download these questions papers

[@brave385]

but i dont get at 19:55 you said the magnitude of unit of vector AO is 1, i dont understand how you got 1 ?

[@1963rzr]

That is one of the reasons they are called unit vectors. The magnitud is always one...

[@joeyGalileoHotto]

Unit vectors ONLY specify direction.

26:41 How come DEy = DE = 392.4 N ... I though DE = (DEy^2 + DEx^2) ^1/2 and we actually didn't find DEx ? Thank you for your explanation if you get a chance to.

[@1963rzr]

I never said "DEy = DE = 392.4 N" Sum of Forces in y must be zero per equilibrium.... If you check the FBD, the only forces acting in 'y' are DE sin 30 and the weight of the lamp (negative) so... DEsin 30 - 196.2=0 and solve for DEActually, DEy is DEsin 30. The X component of DE is explained and used in 27:08

Hi I'm from the Philippines may I ask what is your book?

several books, not a particular one

can you identify some of these books?? my lecturer gets similar exam problems to the examples you use

Sir, good morning, can I ask when does the coordinates and the dot product be used? Thank you.
