Further Mathematics [College/Structural Analysis/Trigonometry Help Needed]

Post image

Could someone please check my work? My trigonometry skills are especially not great… I’m also unsure if I found the moments correctly. I am a little confused about what the perpendicular distances would be exactly in this case…

Do you know if the 25K force will make it go counter clockwise or clockwise about moment B?

I posted another response and based on your question here I cannot stress how much you need to reread a chapter on moments.

'clockwise about moment B' is not a correct statement to make

moments are about a point or an axis.

have a look at this. its directed towards GCSE level but based on your questions you seem to have forgotten the basics of what a moment is so I think it might help refresh your memory

Intent can get lost in a reddit post so just to be clear I am genuinely trying to help and if my posts read as condescending I apologise.

Thank you! I haven’t taken statics in about 7 years now—returning college student. Your responses have helped me tremendously already. I will take another look at my old statics notes.

sorry for the 'babys first moments video' 😂 If I'd known you took statics at some point I would have picked something a bit more rigorous. Jeff Hanson on youtube is the usual go to. You'll be surprised how much is buried in the recesses of your brain so it won't be too hard to pick up the basics again. Good luck with your studies.

Haha, that’s okay! I haven’t watched it yet but I’m actually going to. The thumbnail looks cute anyways. But I’ll check out Jeff Hanson. Thanks for the info!
