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

[@EngineersAcademy2020]

Thanks

[@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)

[@saeedshenwari2267]

Great job 👍

[@EngineersAcademy2020]

Thanks keep watching and share with your friends.

[@abrahamhinojosa1457]

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.

[@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

[@samb.7395]

Could we solve this with method of joints?

[@maramshams673]

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.

[@MMT_Moses]

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