During calibration of an LVDT, the data shown in Table P1.55 were obtained. Using a spreadsheet program, plot the relation between the micrometer reading and voltage. What is the linear range of the LVDT? Determine the calibration factor of the LVDT by obtaining the best fit line of the data within the linear range.

- The assembly shown in the figure consists of an aluminum tube AB and a steel rod BC. The rod is attached to the tube through the rigid collar at B and passes through the tube. The cross-sectional area of the rod is 75 mm2 and the cross-sectional area of the tube is 400 + UV in mm2, where UV is 99. A tensile load of 80 kN is applied to the rod. Take Est = 200 GPa for the steel rod, Eal = 70 GPa for the aluminum tube. Determine: (a) the displacement of end C with respect to end B (i.e., the elongation of the steel rod), (b) the displacement of end B with respect to the fixed end A (i.e., the shrink of the aluminum tube), (c) the displacement of the end C of the rod (i.e., (a) + (b)).arrow_forward16. A structural support made of plastic has to withstand a constant deformation (constant change in dimension) for 80 years at35 C. State what test you would use to know how the stiffness of the plastic has changed. Next describe what data you would collect and what time period you would collect this data. Type of test method More about the test method (choose one below) a. Conduct measurements for 80 years at 35 °C b.Conduct measurements for shorter period of time at 35 °C c.Conduct measurements for shorter period of time at different temperatures below 35 °C d.Conduct measurements for shorter period of time at different temperatures above 35 °Carrow_forwardAt a temperature of 37.4 °C a 0.49-mm gap exists between the ends of the rods shown. At a later time when the temperature has reached 128.7°C, determine the change in length of the steel rod if L = 328.25 mm and M = 215 mm. Round off the final answer to four decimal places.arrow_forward
- Measurements should be reported to the nearest 1000, 100, 10, 1, 0.1, 0.01, 0.001 units, etc., depending on their variability and intended use. Using your best judgment, how should the following measurements be reported? Deformation of a steel specimen during the tension test (in.) Tensile strength of steel (psi) Modulus of elasticity of aluminum (MPa) Weight of aggregate in a sieve analysis test (grams) Compressive strength of portland cement concrete (psi) Moisture content in a concrete masonry unit (percent) Asphalt content in hot-mix asphalt (percent) Specific gravity of wood Distance between New York City and Los Angeles (miles) Dimensions of a computer microchip (mm)arrow_forward1.7 The density of copper is 8.96 g/em'.
