Use the MWFRS Envelope Procedure in ASCE 7-10 Chapter 28, Part 1 to answer this question. Assume that the building meets the conditions described therein. You have been tasked with designing a partially-enclosed building. The mean roof height is 20 ft, and the roof angle is 20 degrees. The basic wind speed provided by the local building authority is 145 mph. Assume that exposure category B is applicable and that the building is not located on a hill or an escarpment. Determine the external pressure coefficient GCpf on Zone 3 for Load Case A.

Use the Simplified Alternative Procedure in ASCE 7-10 Chapter 12, Section 12.14 to answer this question. Assume that the building meets the limitations described therein. A two-story building with the following characteristics has a bearing wall system consisting of light-frame (cold-formed steel) walls sheathed with wood structural panels rated for shear resistance. A certain shear wall in the building is 100 feet long by 18 feet tall and weighs 15 psf. Determine the seismic base shear, V, for the wall.Risk Category ISite Class BSS = 0.75, S1 = 0.30

An object moves with constant acceleration along the +x-axis. The velocity versus time graph is shown in the figure. t1=[t1] s, v1=[v1] m/s, and v2=[v2] m/s. If the position of the object is x = 0 at t = 0, determine the position of the object at t = t1 (in meters).
