Suppose you are climbing a hill whose shape is given by the equation z = 1600 - 0.005x2 - 0.01y2, where x, y, and z are measured in meters, and you are standing at a point with coordinates (120, 80, 1464). The positive x-axis points east and the positive y-axis points north. (a) If you walk due south, will you start to ascend or descend? O ascend descend At what rate? vertical meters per horizontal meter (b) If you walk...
Find the moment of inertia for the cross-sectional shape about the x and y axes, given: L1 = 6 in, L2 = 4 in, L3 = 4 in, LA = 2 in (ans: lx = 1.41 x10° in, ly = 5.9 x10 in) Select problem completion status from drop-down list: Click for List
A long, slender structural steel LE - 29,000 ksil H558 x4x 1/4 shape (see Appendix B for its cross-sectional properties) is used as aL-41.00-ft-long column. The column is supported in the x direction at base A and pinned at ends A and C against translation in the y and z directions. Lateral support is provided to the column so that deflection in the x-2 plane is restrained at mid-height B; however, the column is free to deflect in the x-y...
Given the significance level α=0.095 find the following: (a) lower-tailed ?z value z= (b) right-tailed ?z value z= (c) two-tailed ?z value |z|=
Find the z value that satisties each of the following conditions(report the value of z that comes closest to satisfying the condition). In each case, sketcha standard Normal curve with your value of z marked on the axis. 7. 20% of the observations fall below z. (Sketch the graph and shade the given area) (20% = 0.20)That is, find the z value corresponding an area of 0.20 on the left of it. a) 30% of the observations fall above z....
Suppose you are climbing a hill whose shape is given by the equation z = 1400-0.005x-0.01, where x, y, and z are measured in meters, and you are standing at a point with coordinates (60, 40, 1366). The positive x-axis points east and the positive y-axis points north. (a) If you walk due south, will you start to ascend or descend? ascend descend At what rate? vertical meters per horizontal meter (b) If you walk northwest, will you start to...
