Use the following data to answer questions 1-3. For the beam cross section, assume b- 8.750 in. C- 3.500 in. d-6.125 in. t- 0.875 in. (a) Determine the location of the centroid of the coss-section of the beam measured in inches above the bottom surface of the beam. Round off your answer to the nearest thousandths. M. (сур)

A steel tape standardized at 20degree celcius and supported through out under tension of 90N Was found to be 30.377m long. The tape had a cross sectional area of 55mm^2 and a weight of 73g/m. This tape was used supported at the ends only with a constant tension of 78N to measure a line from A to B in nine segments. The data given in the following table were recorded. Apply correction for tape, length,temperature,pull,sag and tape not horizontal to determine the correct length of the line Difference in Elevation Cm) 0-392 Section Meacured Recarded Distance) Tempergrare A-1 15 1- 2 30 15 0.301 2-3 30 16 O.191 3-4 16 0-255 4-5 30 16 0-38 5-6 30 8.636 6-7 0.782 7-6 30 0-825 8-8 25.348 18 0.578 Sum = 265-348 m
