### Problem: Spring Scale and Salami Weight Measurement

**(a)** A 0.918 kg salami is supported by a cord that runs to a spring scale, which is supported by another cord from the ceiling (see Figure (a)). What is the reading on the scale, which is marked in weight units?

**Diagram (a):** The image shows a salami hanging vertically from a spring scale. The top of the spring scale is attached to a ceiling.

**(b)** In Figure (b), the salami is supported by a cord that runs around a pulley and to a scale. The opposite end of the scale is attached by a cord to a wall. What is the reading on the scale?

**Diagram (b):** The image features a salami hanging on the right side from a cord running over a pulley. The spring scale is mounted horizontally and attached to a wall on the left side.

**(c)** In Figure (c), the wall has been replaced with a second 0.918 kg salami on the left, and the assembly is stationary. What is the reading on the scale now?

**Diagram (c):** The image portrays two salamis hanging, one on each side of a table. The spring scale is horizontal, positioned between the two pulleys at the ends of the table.
