Alex Kogan MSE 410 HW 2 1) A metallic bond is one of the primary bonding types, and it is between the delocalized electrons. The valence electrons are distributed equally throughout the lattice thus creating neutral atoms. The bonding generally lacks direction and is strong enough to cause high melting points for metals. 2) a) The stiffness is defined as the tensile force divided by the deflection (displacement). I have calculated the stiffness for all 13 provided data points.

b) I plotted stress in MPa, which is the force divided by the area (0.0468m^2*π) and then divided by 10 6 . Strain is defined as the deflection divided by the original length, which is
