Homework Statement
[PLAIN]http://img109.imageshack.us/img109/1267/picture2ae.png
[tex]m_1 = 2kg[/tex]
[tex]m_2 = 6kg[/tex]
[tex]R = .25cm[/tex]
[tex]M = 10kg[/tex]
[tex]\theta = 30º[/tex]
[tex]\mu = 0.36[/tex]
Find the acceleration of the system.
Homework Equations
The Attempt at a Solution
[tex]m_1 a = T_1 - m_1 g \mu[/tex]
[tex]m_2 a = m_2 g \sin \theta - m_2 g \mu \cos \theta - T_2[/tex]
[tex]\tau = I a/R = R T_2 - R T_1 \cos \theta[/tex]I solved this system and the result is different from the solution.
What am I missing/doing wrong?Regards
Johnny
