Which of the following statements is not true Vertical curve

Which of the following statements is not true? Vertical curves are found in the vertical plane Horizontal distances are found in the vertical plane Distances in vertical curves are measured in the horizontal plane Vertical distances are parallel to the gravity vector Lets say that I am trying to define the radius of my horizontal curve using the arc definition. As I start walking along the curve starting at the PC and walk 100.000m, where I measure an angle to be 32 degree 33\'34\". What is the radius of this curve in meters? 3.071m 307.152m 17.464m 175.973m Given g_1 = +0.75%, the PVC has a station of 12+32.25\' and g_2 = -4.15%, 1/2 = 500.00\'. What is the grade of the curve at station 14+21.21. -0.18% -0.49% -0.98% -1.85% Which of the following is not true regarding vertical curves? A crest curve will always have a negative rate of change per station A sag curve will always have a positive rate of change per station A vertical curve with both the tangents having a positive grade will always have a positive rate of change per station. All are true Which of the following was not a surveyor? George Washington Thomas Jefferson Theodore Roosevelt Abraham Lincoln
