Refer to the following illustration for Probs. 14 through 15. E FGH BCD RPSS 3700 ft 10+00 C110 2000 CP C100 2500 EP FO5 3700 stake at point K (front) (back) RPSS Reference Point for Slope Stake CP Control Point EP Edge of Pavement - 14 (4 points) The first entry under the double strike line on the coded stake at point K indicates that the (A) excavation required at point H is 1.1 ft (B) finished grade elevation at point H is designed to be 1.1 ft below the elevation of the stake set at point J (C) embankment required at point H is 1.1 ft (D) difference in elevation between point I and point J is 1.1 ft 15 (4 points) The second entry under the double strike line on the coded stake at point K indicates that the (A) excavation at point F is 1.0 ft (B) embankment at point F is 1.0 ft (C) difference in elevation between point G and point F is 1.0 ft (D) difference in elevation between the finished grade at point F is 1.0 ft below the elevation of the stake set at point J 33 (4 points) A soccer field 120 yd in length measures 9.144 mm on an aerial photo. The scale of the aerial photo is most nearly (A) 1:4000 (B) 1:10,000 (C) 1:12,000 (D) 1:110,000 ooLOL

Answer 1

14) (D) difference in elevation between point I and point J is 1.1 ft.

The stake is set at J and the catchpoint (firat entry) elevation at point I is marked as 1.1 ft.

15) (D) difference in elevation between the finished grade at point F is 1.0 ft below the elevation of the stake set at point J.

Second entry shows elevation between grade at F as 1 ft below the stake set at point J.

33) 1: 12000

1 yd = 914.4 mm

Scale is = 9.144 mm: 120 yd

= 9.144 mm : 120 X 914.4 mm

= 1 : 12000
