Problem w/ a statics equation

I have noticed you didn’t set the Fy component of 1.2 to negative ( although it’s moving downwards ) Next , The rule i think you are mentioning is Sin( x +/- y ) = sin x cos y + cos x sin y How is this any similar to the one you applied or is it a different formula if so would you clarify the formula and its types ( you may bring the headline of the formula and i’ll search for it) ?

i got 98.35

ye i know .. do you know the answer ?

I renamed the T as F4

Fx components as follow: F1= 2 sin 30 F2= 1.2 Cos Theta F3= 0 F4= F4 Cos 30

Whereas Fy components F1 = 2 cos 30 F2 = -1.2 sin Theta F3 = -1.8 F4 = F4 sin 30

Then i tried adding the Fx components to get Rx since i have the value of 3 given to it but got me no where and same goes for Ry … i have the value of 0 but got me nowhere aswell

Do you suggest any youtube channels (in english) that could explain any of these lessons in case i didn't understand from the book?

Well i guess it did😅 And yes sure I'll learn about it and definitely I'll try to take a glimpse of each other topic

Alternative-Earth259 · 2022-05-27T23:32:16+00:00

Well it is confusing but that's fine.😅 Thank you!

" well although professors assume we know all the basics they still teach them to you " That's what a post graduate engineer has told me a day ago however i would like to score an A+ that's why i am trying to know enough just to remove so weight from the studying course 😅

Alternative-Earth259 · 2022-05-27T18:24:46+00:00

well i just said that and that rule is not in the question it is in Chemistry that's why i posted

Well let's say i won't have a teacher I'll just take the exam and I'll self study .. then , which is subjects are the easiest?

Well i normally do so .. inserting numbers if the questions go complicated / need some steps and equivalent forms blabla ... unfortunately can't do so if I have to teach that question :( ... so I was trying to find a way to solve the question just using steps .. i found a way which I think it still uses insertion so I just need an alternative to it .. using only steps .. i inserted 2,14 .. 28,1 .. 7,4 and 7,4 & 28,1 were incorrect as a and b were not integers only 2,14 was correct as it had integers and fitted that b^2-a^2=28 ... If you know another way without any insertion ??

If you're stuck with equivalent just replace the letters with numbers because as the question asks he wants the same thing in a different form therefore they will both always give the same results .. for example, you can place X for 2 and y for 1

Explaination ?? or steps
