Dependence on mechanical properties

The mechanical properties of materials are those structures that include the reaction to the load used. Metal switching features determine the scope of the usefulness of the content and establish the expected service life. Machine structures are also used to help distinguish and identify material objects. The most common mechanical properties considered are strength, ductility, stiffness, impact resistance, and resilience to fractures.

Question

A steel tape standardized at 25degree celsius and supported throughout under a tension of 73N was
found to be 30.004m long. The tape had a cross sectional area of 5mm^2 and a weigh of 45g/m. This
tape was used supported at the ends only with a constant tension of 75N to measure a line from A to
B in nine segments. The data given in table 1 were recorded. Apply correction for tape, length,
temperature, pull,sag and tape not horizontal to determine the correct length of the line

A line was measured to be 2682.35m using a 30m steel tape supported throughout its length under a pull of 4.4kg. The mean temperature during measurement is 34 degree Celsius. The tape used has a cross sectional area of 0.03 square centimeters and has a standard length of 20degree Celsius under a pull of 5.5kg. The modulus of elasticity of the tape material is 2 x 10^6 kg/cm^2 and the coefficient of thermal expansion is 0.0000116 per degree Celsius. a. Determine the error due to temperature change. b. Determine the error due to tension. c. Determine the corrected length of the line.
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.
