A level maths, Mechanics 2. Last unit is frameworks, and I do not understand at all. How am I meant to solve these? I'm meant to find all the internal angles.

Any help will be appreciated, cheers..

sounds like an "O" level maths geometry question

Bollocks, meant to say internal forces. Not angles.

Find the forces acting on it (weight most likely). Resolve the vertical force (gravity) in the direction of the struts in the framework. cosine and sine are your friends.

Or something like that.

Vectors isnit? It's simple if it's explained well.

Yeah, but while it gave me a few answers, they didn't feel right.

If you give me a question I might be able to help if you're still stuck (AS Level maths + a maths course since I've been at uni)
