1. Wind blows on the side of the fully enclosed building located on open flat terrain in Oklahoma. Determine the design wind pressure acting on the windward wall, the leeward wall, and the side walls. 2. Classify each of the structures as statically determinate, statically indeterminate, or unstable. If indeterminate specify the degree of indeterminacy.

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
