Previous Page Next Page Page 8 of 8 Question 8 (20 points) Listen Two 25-meter-long wires made of differing materials are supported from the ceiling of a testing laboratory. Wire (1) is made of material "HQ" and has a diameter of 15mm. Wire (2) is made of material "GS" and has a diameter of 7.5mm. When a load of 1000N is applied to its lower end, wire (1) stretches 0.25mm. When the same 1000N load is applied to the lower end of wire (2), wire (2) stretches 0.15mm. (20pts) 1. Draw an illustration of the testing scenario on your paper. (answer on your paper) 2. Calculate and compare Young's modulus (in N/m- ) for both materials. (answer on your paper) 3. Which material has the greater Young's modulus? 4. Which is the stiffer material? A/ Previous Page Next Page Page 8 of 8 f4 0) f6 f7 f8 fg ho @
