1.Compute the atomic packing factor for the diamond cubic crystal structure. Assume that bonding atoms touch one another, that the angle between adjacent bonds is 109.5, and that each atom internal to the unit cell is positioned a/4 of the distance away from the two nearest cell faces

2.A three span continuous beam has spans of 27, 30, 27 feet, total unfactored dead loads are 2,600 pounds per linear foot, unfactored live loads are 2,000 pounds per linear foot. For load combination 1.2D + 1.6L, determine the maximum negative moment in each span and maximum negative moment at each support. remember that live loads shall be placed so as to cause the greatest effect. specify the method that you used to determine the moments
