Suppose I have a rectangular building with five floors, each 10 feet high, 50 feet long in the x direction and 30 feet wide in the y direction. Suppose x is the direction perpendicular to the wind and y is the direction parallel to the wind. Suppose coordinate (0,0) is at the lower left side of the building facing the wind. If I know the wind pressures at each floor level, what would be the coordinates of the resultant wind pressures at each floor level relative to the (0,0) coordinate.

A five-sided closed field traverse has the following distances in meters: AB = 51.766; BC = 26.947; CD = 37.070; DE = 35.292; EA = 19.192. The adjusted angles are as follows: A = 101°03′19″; B = 101°41′49″; C = 102°22′03″; D = 115°57′20″; E = 118°55′29″. The bearing of AB is N 73°00′00″ E. BC is in the S.E. quadrant.The coordinates of the five(5) corners of the traverse have been computed to be as follows: Corner "A" X Coordinate 1000.000 Y Coordinate 1000.000 Corner "B" X Coordinate 1050.019 Y Coordinate 1013.314 Corner "C" X Coordinate 1062.085 Y Coordinate 989.218 Corner "D" X Coordinate 1033.262 Y Coordinate 965.900 Corner "E" X Coordinate 1001.292 Y Coordinate 980.852 The area of the traverse using the coordinate method is 1,857 Square meters. If you used the area computation method we used in class and on the homeworks, the computed number using coordinate method for area computation for corner "C" is_______? Your answer will be in square meters to four (4) decimal place accuracy. |

Design a strap footing to support the two columns. These structural elements are spaced at a distance of 5.4 m center to center. Exterior column is 300 mm x 300 mm and carries a dead load of 250 KN and a live load of 300 KN. Interior column is also 350 mm x 350 mm in cross section and carries a dead load of 360 KN and a live load of 580 KN.
Use f'c = 21 MPa, fy = 276 MPa, and q-all net = 160 KPa. Assume weight of footing to be 9% of total load.

Consider a pipe that branches out into three parallel pipes and then rejoins at a junction downstream. All three pipes have the same diameters (D= 3 cm) and friction factors (f= 0.018). The lengths of pipe 1 and pipe 2 are 5 m and 8 m, respectively while the velocities of the fluid in pipe 2 and pipe 3 are 2 m/s and 4 m/s, respectively.
Solve for the headloss at the junction (m).
