Method of Joints - Analysis of Trusses (🇵🇭 Tagalog 🇵🇭)

[@engrjame]

Hello po, paano po malalaman kapag sin or cos na yung gagamitin?

[@angelomariano2429]

vertical = cos horizpntal= sin

[@engrleir]

It’s a common misconception na pag x cosine tapos pag y sine. Mas tama na cosine ung adjacent tapos sine pag opposite the given angle. For example nakadikit ung angle sa vertical, ibig sabihin ung component adjacent sakanya (ung vertical component) makukuha mo using cosine.

Sir correction lang po i think in joint b, the second equation should be equals to -80. If im not mistaken but still, you arrived at the right answer

[@josephinezanoriaaguilar8898]

-50 bro kasi divided by 2 both side to make the 1/2 as 1 and Multiply the -30 by 2 and the result is -60 and subtract the 110 which is 50 then transpose the 50, that's why it's -50. Sana makatulonG bro 😉
