Figure    9B IN ANSWERING QUESTIONS 9-36 and 9-37, REFER TO FIGURE 9B. 9-36. 9-37. 9-38. 9-39. The steel tape shown is used to lay out the distance from point A to point  B. If  the  thermometer attached to the tape reads 79°F, what is the actual distance laid to offset the effect of change in temperature? 1. 168.09 ft 2. 168.99 ft 3. 169.01 ft 4. 169.07 ft At another time, the steel tape shown is used to measure the distance from point A to point B, but this time,    the  thermometer reads  35°F. How much should you add or subtract to the measurement in order to compensate for the change  in  temperature? 1. Add 0.02 ft 2. Subtract  0.02  ft 3. Add 0.04 ft 4. Subtract  0.04  ft A  3-pound,    100-foot tape is used to measure a distance of 60 feet. If the chainman maintained a pull of 20  pounds,    what  is  the  correction of sag? 1. 0.02 ft 2. 0.03 ft 3. 0.04  ft 4. 0.05 ft When is slope correction subtracted from  the  taped  slope  distance? 1. When taping uphill only 2. When taping downhill only 3. When  applying  the  slope correction  formula  for  10% slopes  Only 4. Always 9-40. When determining accurate slope correction, what is the maximum slope for which you should use this formula? 1. 5% 2. 10% 3. 20% 4. 30% 9-41. The difference in elevation between two points is 4.0 feet. If the slope  distance  between  the  points is 125.00 feet, what is the horizontal   distance? 1. 124.936 ft 2. 124.978 ft 3. 125.032 ft 4. 125.064 ft 9-42. Rules pertaining to the taking of chaining notes require that the notes reflect which of the following  qualities? 1. Completeness 2. Accuracy 3. Legibility 4. All of the above 9-43. What is the proper way to correct an error in field notes? 1. Erase  the  error 2. Blot out the error 3. Draw a line through the error and  enter  the  correct information  above 4. Circle and initial the error IN  ANSWERING  QUESTION  9-44,  REFER  TO FIGURE 9-44. 9-45. 12-17 IN YOUR TEXTBOOK. What  three  types  of  corrections  are made in the slope chaining measurements? 1. Tension, temperature,  and humidity 2. Altitude, temperature,  and  wind 3. Hub,  bench  mark,  and  station 4. Tape,  temperature,  and  slope In which of the following ratios do the lengths of the sides indicate that the triangle is a right triangle? 1. 10:15:20 2. 18:24:30 3. 20:30:40 4. 25:30:40 62
