Transcribed Image Text:

An aluminum alloy cylindrical rod is pulled to failure in a tension test. The rod is 20 cm in length with a diameter of 0.250 cm. The rod is loaded with a 5000 N weight. If the diameter decreases to 0.210 cm, Determine (a) the engineering stress and strain at this load (b) the true stress and strain at this load 4) A concrete has a height of 5 meters and has a unit area of 3 m3 supporting a mass of 30,000 kg. Determine (a) The stress (b) The strain (c) The change in height. Acceleration due to gravity (g) =10 m/s2. Young's modulus of concrete = 20 x 109 N/m2.
