**Problem 5.62**

In the figure (Figure 1), a worker lifts a weight \( w \) by pulling down on a rope with a force \( \vec{F} \). The upper pulley is attached to the ceiling by a chain, and the lower pulley is attached to the weight by another chain. The weight is lifted at constant speed. Assume that the rope, pulleys, and chains all have negligible weights.

**Figure**

The diagram shows a pulley system. The upper pulley is connected to the ceiling and supports the lower pulley and weight via a chain. The worker pulls on a rope that goes through the pulleys to lift the weight.

**Part B**

In terms of \( w \), find the tension in the upper chain.

*Express your answer in terms of \( w \).*

The question requires an understanding of how tension operates in a pulley system and how it relates to lifting a weight with a constant velocity. The goal is to express the tension in the upper chain in terms of the weight \( w \).

**Problem 5.62**

In the figure (Figure 1), a worker lifts a weight \( w \) by pulling down on a rope with a force \( \vec{F} \). The upper pulley is attached to the ceiling by a chain, and the lower pulley is attached to the weight by another chain. The weight is lifted at constant speed. Assume that the rope, pulleys, and chains all have negligible weights.

**Figure:**

The diagram illustrates a system of two pulleys. The upper pulley is connected to the ceiling with a chain, and a rope passes through it. Below it, a second pulley is visible, connected to the weight by another chain. The slack chain and pulley arrangement suggests that the weight is being lifted vertically by exerting a downward force on the rope.

**Part A**

In terms of \( w \), find the tension in the lower chain.

**Express your answer in terms of \( w \).**
