The past chapter proposed the continuous floating constraint and buckling column concept. In this chapter, a test setup is proposed to investigate its loading nature and validate the concept. A series of tests are performed, and the results are presented and discussed. The results of the tests conducted in this chapter will serve as measures in assessing the strengths and flaws of the initial concept, and point towards potential solutions. This group of tests varied two geometric parameters: system length, and constraint gap. The tests were performed on a universal testing machine. From this, load-displacement, continuity of the curve, curve stability, and hysteresis may be investigated. The ultimate goal here being to validate this concept and to use this information to predict and narrow the scope of system configurations. 3.2 Test Setup The system consisted of three overall parts (Figure 3.1). The grips which were the connection points between the column and the Instron. The top grip was connected to the load cell, and where displacement was imposed. The bottom grip attached to a plate that attached rigidly to the Instron base via 6 3/8in-24 bolts. The end conditions are clamped-clamped as this is what they will be closest to in the final system. The grips were machined from steel. The column was clamped into the grips, and the…

EXERCISE 1 As Wenger and Potter (2015) assert, “stand-ups can serve several functions, so it’s important to know in advance what you’re trying to accomplish with an on-camera segment” (p. 284). Personally, I would need to prepare myself thoroughly and conduct some research of my own to learn more about the topic at hand. My goal as a reporter is to establish credibility on the subject and be able to project confidence to the audience (Wenger and Potter, 2015). According to Wenger and Potter…
