Chapter 6, Problem 29PCE

Predict/Explain (a) Referring to the hanging planter in Example 6-10, which of the three graphs (A, B or C) in Figure 6-46 shows an accurate plot of the tensions T₁ and T₂ as a function of the angle θ? (b) Choose the best explanation from among the following:

Figure 6-46

Problem 29

1. I.            The two tensions must be equal at some angle between θ = 0 and θ = 90°.
2. II.            T₂ is greater than T₁ at all angles, and is equal to mg at θ = 90°.
3. III.            T₂ is less than T₂ at all angles, and is equal to 0 at θ = 90°.
