An atwood machine holds two masses at its ends by a massless rope. m1 and m2. Assume the pully is frictionless. 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.
