Assignment #2 - Breaking the Bucket of Bolts

  We were given four types of bolts, and instructed to break them. Me and my classmate torqued each bolt and recorded the strain on the bolts in pounds when the bolt was torqued to its specified torque. We then continued past the set torque to find how much the bolt could take before breaking, and recorded the max torque and tensile strength in pounds. This assignment gave me valuable knowledge, not only that different grades of bolts and their different strengths, but also, what it feels like when you've gone to far and broken a bolt. We also placed the bolts in a "bolt stretcher" for lack of a better description. It would display the amount of stretch in pounds that were acting on the bolt.
