A 50 m tape of standard length has weight of 0.05 kg/m, cross section is 0.04sq cm, E is 2.10 x10 6 kg/sq cm. The tape is of standard length under a pull of 5.5 kg when supported throught its length. This tape was used to measure a distance AB and was recorded to be 458.65 m. at time of measurement the pull applied was 8 kg with the tape supported only at its endpoints and temperature observed was 18°C. Find the sag correction for the measured line
HI! HELP ME WITH THIS PLEASE. TYSM
Jisoo used a 40 meter steel tape in measuring an inclined distance on a gentle slope. The sloping distance was recorded to be 440 meters long. The difference in elevation between the initial point and the end point was found to be 32.49 m. The 40-meter tape is of standard length at a temperature of 20 °C and a pull of 34 N. During measurement, the temperature reading was 44 °C and the tape was supported throughout its length with an applied pull of 82 N. The cross-sectional area of the tape is 1.54 mm^2 and the modulus of elasticity is 200 GPa. The tape has a mass of 0.68 kg. Determine the corrected horizontal distance in meters. Round off to two decimal places.
A steel tape is 100.00 ft long and has a weight of 0.0225 lb/ft and is used to measure a line from A to B in two segments (one full tape length and one partial tape length), supported at the ends only for each of the two segments. The recorded distance is 181.83 ft. The pull at the time of measurement is 12 lb. What is the length of the line corrected for sag? (Assume that no other tape corrections need to be applied.)
Determine the angle measured clockwise from the major principal axis to the x axis of the section, in degrees.
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.
