hanging wire made of an alloy of aluminum with diameter 0.05 cm is initially 3.0 m long. When a 7 kg mass is hung from it, the wire stretches an amount 1.69 cm. A mole of aluminum has a mass of 27 grams, and its density is 2.7 g/cm3. Based on these experimental measurements, what is Young's modulus for this alloy of aluminum? Y= ____________N/m^2. As you've done before, from the mass of one mole and the density you can find the length of the interatomic bond (diam
