Situation. A line on the xy-plane has an equation 5x + 12y = 60. A uv-plane of the same origin has its u-axis rotated at an angle of +arctan (4/3) from the x-axis.
(1) Find the uv-coordinates of the y-intercept of the given line.
(2) Find the uv-coordinates of the x-intercept of the given line.
(3) Find the equation of the given line in the uv-plane.
Situation. The following is a set of notes of the earthwork of a road embankment. Sta 5 + 040: 12/-3, -5, 24/-9; Sta 5 + 140: 15/-4.5, -7, 30/-12. If the width of roadway is 12 m and the side slope is 2:1…
(1) Determine the volume of earthwork by end area.
(2) Determine the volume of earthwork by prismoidal formula.
(3) Determine the volume of earthwork by prismoidal correction.
