1. The problem statement, all variables and given/known data A 33.5 kg person stands on a 67 kg platform. He pulls on the rope that is attached to the platform via the frictionless lower-right pul- ley. He pulls the rope at an angle of 35◦ to the horizontal, as shown in the figure below. Assume: g = 9.8 m/s2 . Ignore friction. The platform remains level. [PLAIN]http://img201.imageshack.us/img201/5122/010011.png [Broken] (a) If he pulls the platform up at a steady rate, how much force is he pulling on the rope? (b)In Part 1 we assumed that the platform re- mains level. This is a bad assumption. However, if the man were pulling straight up on the rope, the forces will be balanced and the platform should remain level. 1. This is a good assumption. 2. Cannot be determined. 3. This also is a bad assumption. 2. Relevant equations Sum of Fy= T-Mg=0=> Mg=N, where M=m1+m2 Sum of Fy= N-Mg+Fsintheta=Ma Sum of Fx=Fcostheta=0 3. The attempt at a solution So I know T7=T6, does T7 also equal T2? Does T5= T7+T6? Does T3=T1+T2? What equation can I use to calculate T1?
