A 1.19 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? 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? In Figure (c) the wall has been replaced with a second 1.19 kg salami on the left, and the assembly is stationary. What is the reading on the scale now?Explanation / Answer

T = w
T = 1.19 * 9.8 = 11.662 N
The tension is the same in each case because it is exactly balancing the weight
