Question in attached file

OpenStudy (anonymous):

here

OpenStudy (anonymous):

is T, Tcos27

OpenStudy (ujjwal):

yep! it is Tcos27.. I missed it in my earlier diagram! So, now you have it. Equalize forces.. That's it! You need to find T

OpenStudy (anonymous):

why is mv^2 / r pointing outwards?

OpenStudy (anonymous):

lol

OpenStudy (anonymous):

for fun..

OpenStudy (ujjwal):

because that is centrifugal force.. We need an inward centripetal force to balance it which is provided by Tcos27+Fsin27 F is aerodynamic lift! you have relations: Fcos27=mg+Tsin27 Fsin27+Tcos27=(mv^2)/r Solve them|dw:1349327285279:dw|

OpenStudy (anonymous):

alright thank you!!

OpenStudy (anonymous):

whatever.

OpenStudy (ujjwal):

Finally i made a correct diagram in three attempts! Well the last one (which is the only remaining now) is correct!
