Bah I say. ;) I'm so confused... A "swing" ride at a carnival consists of chairs that are swung in a circle by 15.0-m cables attached to a vertical rotating pole at an angle of 60.0 degrees to the pole. Suppose the total mass of a chair and its occupant are 179kg. (a) Determine the tension in the cable attached to the chair. (b) Find the speed of the chair. Ok, so I'm looking at part a. I have a nice drawing going, a right triangle with the lower right dot representing the chair, and a 60 degree theta up top. I drew a force diagram, which you can see at http://pics.bbzzdd.com/users/johnjohn/no19.JPG (you have to copy and paste the link, it's not gonna work otherwise). And now I have no idea what to do next. :( I know how to find the Fg and FN obviously, but then how do I use that to find FT? Thanks guys. I have a test tomorrow, hopefully I won't be posting here too much.
