Do they basically just mean find the tension ?
What does "the reaction of the bead on the wire" mean ? Is it the sum of the tension and parallel component of weight or just the tension or what ?Last edited by member910132; 20-06-2012 at 19:40. -

Re: M2 Help - Exam TomorrowIf you're thinking about the bead being attached to the centre via a light rod, rather than being on a wire, then yes.(Original post by member910132)

NOTE: I say rod rather than string since the reaction could be away from the centre if the bead isn't moving fast enough. -

Re: M2 Help - Exam TomorrowThis question completely stumped me and I still don't get it. I can do all the maths fine but I have no idea what they actually mean by the normal from the bead on the wire.(Original post by ghostwalker)

Re: M2 Help - Exam TomorrowDraw a tangent to the circle at the bead, then draw the perpendicular to that tangent. And you now have the normal they are referring to.(Original post by member910132)

Corresponds to the tension/compression in the ficticious rod of my previous post.
