Acceptance sampling is a method that uses small random samples from incoming shipments of products to assess the quality of the entire shipment. Typically, a random sample of size n

A 100 ft steel tape standardized at 68 °F and supported throughout under a tension of 10 Ibs was found to be 100.2 ft long. The tape had a cross sectional area of 0.009 in? and a weight of 0.03 Ib/ft. The tape is used to measure a horizontal distance (AB) and the measured length comes out to be 300 ft. CALTRANS plans a new ramp to connect Nutwood with US57. The ramp starts from point A (on Nutwood) to C (on US57) wherein point C will be vertically above point B (a current point on Nutwood that will get buried by ramp). The must have a smooth 4% grade, thus the tape will be used fully supported. Determine the correct slope distance to be measured (i.e. length AC) if a pull of 15 Ibs is used and the temperature is 96 °F.

4) If the bearing of AB is N 38°45'10" E, compute the bearings of the remaining sides.Provide solutions for the clockwise and counterclockwise directions. (Show all work and put final answers in boxes provided) (10 pts)

33 A surveyor counted the number of paces required to cover a 250-ft distance. The results were as follows: 95, 93,97, 98, and 92 paces. Then an unknown distance was stepped off four times, requiring 115, 118, 116, and 117 paces.3.Determine the average pace length and the length of the(Ans.: 2.632 ft, 307 f)second line.

-14Three designs have been proposed to improve traffic flow at a major intersection in a heavily traveled suburban area. The first alternative involves improved traffic signaling. The second alternative includes traffic-signal improvements and intersection widening for exclusive left turns. The third alternative includes extensive reconstruction, including a grade separation structure. The construction costs, as well as annual maintenance and user costs, are listed in the following table for each alternative.Determine which alternative is preferred based on economic criteria if the analysis period is 20 years and the annual interest rate is 15 percent. Show that the result is the same using the present worth, equivalent annual cost, benefit-cost ratio, and rate-of-return methods.

2.31 An engineering student claims that a country road can be safely negotiated at 65 mi/h in rainy weather. Because of the winding nature of the road, one stretch of level pavement has a sight distance of only 510 ft.Assuming practical stopping distance, comment on the student's claim.

3.) The interior angles of a pentagon were measured using an instrument with an angular error of ± 1". What is the estimated error of the sum of the interior angles?

3.4 A surveyor paces a 400-ft length four times with the following results: 140, 143, 141, and 142 paces. How many paces will be necessary for this surveyor to lay out a distance of 525 f?

Q2. The daily mean flows in a river for three consecutive years are given in Table 2 by class interval along with the number of days (N) the flows belonged to this class. What are 50% and 75% dependable(i) mean daily flows and (ii) mean annual flows for this river ?

6- Calculate the coordinates: Angle ( B ) = 32° 30' 40“ The Azimuth of line ( AB ) = 120° 30' 25“ Coordinate A = ( 220 N , 150 W) Coordinate A = ( 220 N, 150 W) Length ( CD ) = 150 m Length ( BC ) = 200 m Length ( AB ) = 106 m
