brother you cant fathom how much you're carrying my GPA thanks a bunch

[@arslanriaz4571]

you are doing a great job, you have complete grip on this subject, May you get all what you deserve and more....

[@EngineersAcademy2020]

Thanks

Why didnt do for joint A?

[@samb.7395]

Could we solve this with method of joints?

[@chubilog624]

wait Im confuse do you use methods of sections or method of joints? and Thank you for lesson

[@madison_cole]

Since you had to find all the forces in each member, its better to use method of joints, which is what he used here. Method of sections is better when you only need to find the forces in a few members

[@marwahmirajkar2934]

at joint E I'm getting the same answer for the y component as yours when subtracting 5 (5kn at EA) instead of adding 23 (Ey)

[@peace-pj8lv]

im still confused why sometimes for Fy use sin and sometimes use cos? what's the difference and can you tell me when I should use sin or cos? thank you

Great job 👍

[@EngineersAcademy2020]

Thanks keep watching and share with your friends.

why cant we use the 3 4 5 triangles instead of sin59.04 ??

[@EngineersAcademy2020]

This is not 3 4 5 triangle. CE member length is 5m.

[@nathanturner5972]

you can

Why is DE in compression? thats the part the confuses me because i always just assume tension but if i get - then its the opposite, is this wrong?

[@EngineersAcademy2020]

Ur doing it right, always assume tension.

[@JT-oz7yn]

I would say DE is in compression because of the horizontal force of DC, which acts as DCsin(theta) downwards on DE aswell, pushing into point E.

[@GamerKumaa]

FDE is pointing towards D, and we found FDE to be positive in that orientation, so FDE is compressing the joint.

Why we assume the
