1.The thickness of a gage block is measured five times using an instrument that has a resolution of 0.001 cm. The following measurements are obtained (in cm): 1.100, 1.110, 1.090, 1.095, and 1.105. The true gauge block thickness is known to be 1.050 cm. Use this information to answer the following questions: a. What errors or sources of measurement error can be identified in the example? (Hint: there are three). Identify each one as a random or systematic uncertainty. b. Estimate the magnitudes of each of these uncertainties. Wherever possible, estimate random uncertainties at a 95% probability/confidence level. c. Based on the uncertainties determined in part b, estimate the overall uncertainty of a measurement obtained by this instrument.

To measure the perimeter of a triangle, the lengths of the AB, BC and AC sides are measured using a caliper with a resolution of 0.05 mm. Performing a single measurement for AB, BC and CA, the values AB = 50.20 mm are read; BC= 55.15 mm and CA= 40.65 mm. Determine the perimeter (P) of the triangle with its uncertainty (uP) and express the result in m. a) P±uP= (0.146000 ± 0.000050) m b) P±uP= (146,000 ± 0.050)x10-2 m c) P±uP= (146.00 ± 0.05)x10-3 m d) P±uP= (0.146 ± 0.050) m e) P±uP= (146.0 ± 0.05) m
Calculate the average fall time and standard deviation using the data above. Average - 1.5s Stdev- 1.85s Use the average fall time and one of the kinematic equations to determine the height of the building. Add the standard deviation from step 1 to the average fall time from step 2. This represents a “maximum fall time.” Use this time to calculate the “maximum” height of the building.

Pressure distribution measurements are made on a two-dimensional wing model placed in a wind tunnel. The difference between the static pressure sockets on the surface and the static pressure of the free stream is measured. 30 data is taken at each measurement point. The average of the values measured from one of the sockets near the trailing edge was calculated as 2.30 Pa, and the standard deviation was calculated as 2.65 Pa. After applying the Chauvenet criterion to these measurement values, it was decided to eliminate 3 measurements and the new mean value was found to be 2.18 Pa and the standard deviation was 2.42. It was verified that the unexcluded data fit the normal distribution curve. Data above how many Pa and below how many Pa were eliminated? Estimate how many data have negative value (?<0) after elimination.
