All answers must be in complete sentences.
1. Calculate the weight of the object (or objects) held just prior to structural failure. Show your setup. (Remember, if you held the paper, then the small book, and then the large book, but broke when you placed the physics book on it, you only successfully held the large book. You would use its mass only to calculate weight held.)

2. Calculate the efficiency of your structure by comparing the maximum mass held by the structure to the structure's mass. This is simply a ratio and will be a number greater than one. Show your setup and your answer.

3. What happens to the structure when the normal force is less than the object's weight?

4. Which part of your structure broke or collapsed first? Why do you feel the structure broke or collapsed at this point? What would you do to make your structure stronger at this point?
