Statics: Lesson 4- Vector Addition, Triangle Rule, and Cartesian and Vector Notation

[@Orangeyougladx3]

After having a mental breakdown because I could not get these problems...you explained them so easily it made me feel a lot better. I wish all static’s teachers were as caring as you

How’s dynamics ?

[@SHANNONDOHERTY-ns8mb]

The way you are able to explain things in laymans terms and make them understandable is such a refreshing change from the professors at university! I finally feel like I understand the conceptual side of what it is I am doing. Thank you!!!!

The world needs more teachers like you ❤️

I paid $3k for the same class with a professor not half as talented.

[@bobbyjohnson6687]

It's called paying your dues. If you don't like how much they cost then attend community college first. Companies can't assume you know how to do physics because you told them you taught yourself. Accreditation isn't free. In comparison to the money you will make once you get your degree, it is actually very cheap. Think about the bigger picture. If you're a company and you want to gain government contracts. You need to show that you have 'qualified' individuals to complete the task.

[@eddief1984]

Jeff - I love your videos. I'm studying for my FE after being out of school for a lifetime. Your videos are helping me bring back the stuff I've forgotten. Keep em coming!

Easy, Peezy, Lemon squeezy! Awesome explanation with breaking down vector addition to its simple components and how they relate between the different systems!

[@engonodira2177]

Can you help me to find a book explain that..I search alot but can't find

[@blizzylikesglizzy4059]

Mr. Hanson is pushin P! Learned more in 20 minutes than in my statics class

[@abbeycampbell4373]

My first quiz in statics was on problems like these. I failed the quiz. I found your videos and you explain them in a way I can really understand. You are a legend thank you so much.

[@assa8248]

Man man man I truly admire your talent in teaching and thanks for the effort to put this wonderful course here for us to study and enjoy.

[@georgesadler7830]

DR. Hanson, this is fantastic demonstration of solving for the resultant in two different ways. The Cartesian Coordinates way is very straight forward in comparison to Polar Coordinates way. Problem solving is the key in all science and engineering classes.

[@haziqhaiqal5830]

Thank You Sir. My lecturer took 4 hour to teach this and i still dont understand it. But you took 23 minutes only to make me fully understand it.

[@dylanellul7146]

Thank you very much for doing these videos. Keep on doing the great work as you are helping lots of people who didn't understand this topic at University. We need more people like you in this world.

Jeff Hanson is the best thing on internet or in real life!

[@hyypersonic]

9:58 That joke made me laugh a lot harder than it should've hahahaha. I wish all my professors taught like this man.

thanks God for the vector light at 11:53

[@leoslaima7049]

I feel blessed if you are my teacher

[@Peter_1986]

One very convenient way to calculate resultant vectors on calculators is to treat them as complex polar vectors; for example, this problem can be solved by calculating 40∠25° + 60∠45°. You can also use the functions "Abs" and "Arg" to solve the magnitude and the direction.

[@manuboker1]

Wonderful Lectures ! Thanks.

This man is a life saver

[@bluehornet6752]

Statics is magnificent. Dynamics is too of course, but if you don't get the Statics...you'll never get the Dynamics. Throw in some Calculus and also some Differential Equations, and you're well on your way!

[@medicisounds1384]

HOLY PHUCK, you blew my mind with that. The cartesian method seems easier to me...But when is the cartesian method not proper to use?

[@rondavidfesalbon4843]

Thank you Dr. Hanson

Gr8 work, boss u make things very easy.

[@thegreatest1176]

The expression for the cartessian vector doesnt makes sense when you add Fy+Fx=F (resultant). Its Fy2+Fx2=F2 (resultant)

Please Mrs Jeff Hanson can you solve another example about this subject

[@johnnycastro7110]

Where did he grab 135 from???

[@r.ulquiorra4883]

I feel stupid but i have a question where did 135 at 3:03 come from. I mean how did he know or how can he tell or say that must be 135° help

[@theonlycrafter5580]

The 135 degrees he marked is on the same line of action as the 45 degrees. Supplementary angles sum to 180 degrees, so take 180 minus 45 degrees, which gets you 135 degrees. I would recommend watching his Lesson 4 video, he gives 8 pieces of trig review and an example, and includes him briefly covering this exact concept (in the lesson 4 case 4 example, he has angle 42 degrees, and 138 degrees as the supplementary angle, to form 180 degrees). Hope this helps.

I really like your videos and teaching style, but do you really need 6 ads on a 20 minute video? It's quite distracting..

[@gonfreecs9591]

Bruuh, he is teaching u these lessons for free. Just help him gain more profit coz he deserves it

[@valeriu-iuliansandu-grigor6490]

if you are a student premium is cheap as peanuts:) and besides, I would pay anything to get rid of the ads, and it's totally worth it:)

After using sin law angle is not 12 it's 34.17 +25 = 59.17 Degrees

my calculator consistently got 99.41N instead of 98.54. not sure if that will kill me on a test. not sure what i'm doing wrong.
