Hi guys, this question is driving me up the wall because I always thought pulley system questions were easy and enjoyable to do, but this one refuses to cooperate! The question: Someone exerts a force F directly up on the axle of a pulley. Two objects, m1 of mass 1.2kg and m2 of mass 1.9kg, are attached to the opposite ends of the string, which passes over the pulley. The object m2 is in contact with the floor. a) What is the largest value the force F may have so that m2 will remain at rest on the floor? b) What is the tension in the string if the upward force F is 110N? c) With the tension determined in part b, what is the acceleration of m1? Now, for part a I added the applied force to the gravitational force of m1 since I figured that both forces are pulling up on m2, and I came up with 6.68N. For part b, I'm confused because I don't know how the upwards force on the pulley is distributed between the left and right weights. I've tried a bunch of different things, but I can't get the tension force to be equal on both weights, telling me there's a problem. Can anyone help? Thanks.
