An atwood machine holds two masses at its ends by a massless rope. m1 and m2. Assume the pully is frictionless.(adsbygoogle = window.adsbygoogle || []).push({});

What will the magnitude of the tension(T) go to as m1 goes to infinity but m2 stays the same?

Im very lost on this problem. I have drawn a free body diagram showing m1g and m2g pointing downwards and T pointing upwards.

I have derived two equations

[tex]m_1g-T=-m_1a[/tex] where m1 is going down. I subtracted T from m1g because m1g is much bigger.

[tex]T-m_2g=m_2a[/tex] where m2 is going up. I did this because T should be greater than m2g. i think.

but apparently thats not right, and I dont know why.
