**Give the correct tension, T, in the marked rope for each situation. The rope is held so the system is stationary. All ropes and pulleys are massless and frictionless.**

A) T = W

B) T = W/2

C) T = W/3

D) T = 2W

E) T = 3W/2

F) T = 2W/3

G) T = W/7

H) T = W/5

I) T = 2W/7

J) T = 2W/5

1) I figure that the two pulleys holding the weight W each have a tension of W/2, making the first

**B) T = W/2**

2) The three pulleys holding the weight W each have a tension W/3, and the pulley holding the two pulleys connected to the weight must have a tension of 2W/3, making the second

**F) T = 2W/3**

3) The three pulleys holding weight 2W each have a tension 2W/3, and the pulley ropes holding those pulleys each have a tension of 2W/3, divided by 2 = 2W/6 = W/3. This makes

**T = W/3**

4) I'm not quite sure how to do this one

Thanks for your help!
