In the picture below you can see that a big mass with a weight of 100 Newtons that sits on a scale obviously causes the scale to read 100 Newtons. In the situation below that, the same scale is held vertically in place (not moving) by two people pushing on it from the front and back, each with a force of 100 Newtons. 100 N Scale reads 100 Newtons 100 N 100 N 1. What do you think the scale reads out for this second situation? 2. Draw a free body diagram for the scale in the top picture and for the scale in the bottom. Show both of them side by side here in the discussion. 3. Is there any true difference between the two FBD other than the orientation? What does that tell you about what the scale should read in the second situation?

Question
![In the picture below, you can see that a big mass with a weight of 100 Newtons that sits on a scale obviously causes the scale to read 100 Newtons.
In the situation below that, the same scale is held vertically in place (not moving) by two people pushing on it from the front and back, each with a force of 100 Newtons.
[Diagram]
- The first diagram shows a mass labeled "100 N" sitting on a scale, with an arrow pointing to the scale that reads "Scale reads 100 Newtons."
- The second diagram illustrates two opposing forces labeled "100 N" each, acting on a vertically held scale.
