1.An overpass is being built over the PVI of an existing equal-tangent sag curve. The sag curve has a 70 mph design speed and G1 = -6% G2=+3%. Determine the minimum necessary clearance height of the overpass and the resultant elevation of the bottom of the overpass over the PVI. (Ignore cross sectional width of overpass?

2.For maximum undercooling, calculate the size of the critical radius and the number of atoms in the critical nucleus when solid copper forms by nucleation.
