A swing ride at a carnival consists of chairs that are swung in a horizontal circle by 12.0 m cables that are attached to a vertical rotating pole, as the drawing shows. Suppose that the total mass of the chair and it occupant is 220 kg.
i need just the free body diagram

and how did u get t cos 65 because that is y coordinate right so it would be t sin 65 ?

can u plz help me with this

The chair doesn't touch any surface right? Then there's no normal force. To decide choosing cos or sin, you need to know what angle is given first.

JakeV8Best ResponseYou've already chosen the best response.1
I don't think you need a normal force for this one. (yeah, what @imron07 said!)

what do u mean by what angle
 one year ago

JakeV8Best ResponseYou've already chosen the best response.1
For the cos and sin relations, don't think of the ycoordinate... just look at the diagram and remember that cos = adj/hyp and sin = opp/hyp . You should see it as @imron07 drew it...

yes i know that cos =... and sin=.. but ..

can u draw it @JakeV8

JakeV8Best ResponseYou've already chosen the best response.1
I can't tell what you are asking... @imron07 has the right diagram. The vertical component of the force exerted by the 12m line is T cos(65) because T is the hyp and the vertical component is the adjacent side.

glad to help. I'm pretty out of practice on these, but the diagram helped me remember a little.

imron07Best ResponseYou've already chosen the best response.1
Yes, you can find T then.

\[T=\frac{mg}{\cos65}=5101N=5.1\times10^3N\]

Actually, you can omit the minus sign:\[v=\frac{Tr\sin65}{m}\]where r equals:\[r=l\sin65\]dw:1350338783066:dw

imron07Best ResponseYou've already chosen the best response.1
sorry,\[v=\sqrt{\frac{Tr\sin65}{m}}\]

how can i omit the

the centripetal force is radially inward. This force itsel is minus, so: \[\frac{mv^2}{r}=T\sin65 \]
