Homework Help: Physics-Mechanics

Posted by Genevieve on Wednesday, September 22, 2010 at 8:21pm.

A pulley is massless and frictionless. 3 kg, 2 kg (on the left), and 6 kg (on the right) masses are suspended What is the tension T1 in the string be-
tween the two blocks on the left-hand side
of the pulley?


Can I solve this like if it was two masses?

My prof gave an example T=m1g=m1a
m2g-t+m2a
then we solved for T in equation one and plugged it into equation two... in that problem the Tension was the same on both sides but in the picture on the problem they have labeled them T1, T2 and T3 so I'm not sure
