Hey im not sure where to post this but i'm stuck on this question that i haven't really learnt yet. Can someone show me the full working out and which points to take moments from etc. Somehow i can't attach the doc so whoever has the time to help, tell me your email and i'll send it. I've tried to upload here, but it says upload failed.
Thanks ^^

be more specific, you're basically asking us to teach you the whole topic.

if you're taking moments, try to do so at points in which the forces 'go through' these points, thus allowing them to be neglected
