9-28. In which of the following situations  should  the  breaking  tape method  of  measuring  be  used? 1. Determining  the  horizontal distance between points on terrain  havinq  a  6-to-1  slope ratio 2. Measuring the width of major access  roads 3. Measuring horizontal distances in  heavily  wooded  and obstructed  areas 4. All of the above 9-29. A two-man party is using the breaking chain-procedure and a 100-foot tape to chain a line on a steep slope. When,    if ever, does the  rear  chainman  give  the  front chainman  a  chaining  pin? 1. Each time a 25-ft distance only is  measured 2. Each time a 50-ft distance only is  measured 3. Each  time  an  even-foot  distance of less than 100 ft is measured 4. Never Figure    9A IN  ANSWERING  QUESTION  9-30,  REFER  TO FIGURE  9A. 9-30. Assume that you continue measuring up the slope with a 100-foot tape. The head chainman is holding zero at point D. What  is  the  horizontal distance  between  points  C  and  D? 1. 10 ft 2. 15 ft 3. 25 ft 4. 30 ft 9-31. The standard error of a 100-foot tape can be determined in which of the  following  ways? 1. By  calibration  by  the  Bureau  of Standards 2. By comparison with a length of a calibrated 100-foot tape 3. By comparison with a known 100-foot  distance 4. By each of the above means 9-32. By calibrating a tape, you should remember that the standard tension and  corresponding  temperature  for  a 100-foot  tape  supported  throughout is 1. 5 lb, 65°F 2. 10 lb, 68°F 3. 15 lb, 68°F 4. 20 lb, 65°F 9-33. A 100-foot tape has a standard error of 0.003 feet. What is the total error for a taped distance of 471.56 feet? (Round off to the nearest 0.01 foot.) 1. 0.00  ft 2. 0.01  ft 3. 0.02  ft 4. 0.05  ft 9-34. Under standard conditions, a tape indicates  100.00  feet  when  it actually  should  measure  99.996 feet . Using this tape, how far should you measure to set a point 450  feet  away  from  another  point? 1. 449.96 ft 2. 449.98 ft 3. 450.02 ft 4. 450.04 ft 9-35. A tape has a standard error which causes  it  to  indicate  99.996  feet when it is actually measuring 100.00  feet. What is the actual distance between two points if the taped  distance  is  259.05  feet? 1. 259.04 ft 2. 259.05 ft 3. 259.06 ft 4. 260.00 ft 61
