A line was found to be 2865.35m long when measured with a 30-m tape under a steady pull of 6.5kg at a mean temperature of 30°C. Determine the correct length of the line if the tape used is of standard length at 20°C under a pull of 5.5kg. Assume the cross-sectional area of the tape to be 0.025cm2, elastic modulus as 2.10x10°kg/cm², and coefficient of thermal expansion to be 11.6x10-/°C.

Problem 1.4. A tensile test was conducted on a mild steel bar. The following data was obtained from the test : (i) Diameter of the steel bar (ii) Gauge length of the bar (iii) Load at elastic limit (iv) Extension at a load of 150 kN. (v) Maximum load (vi) Total extension (vii) Diameter of the rod at the failure Determine : (a) the Young's modulus, = 3 cm = 20 cm = 250 kN = 0.21 mm = 380 kN = 60 mm - 2.25 cm. (c) the percentage elongation, and (b) the stress at lastic limit, (d) the percentage decrease in area.

The tensile test has been performed on a 50 mm long steel tube having 18 mm external diameter and 12 mm internal diameter. The axial load of 2 kN produced a stretch of 3.36 x 10-³ mm and a lateral contraction of the outer diameter of 3.62 x 104 mm.

A bar specimen of 36 mm diameter is subjected to a pull of 90 kN during a tension test. The extension on a gauge length of 200 mm is measured to be 0.089 mm and the change in diameter to be 0.0046 mm. The Poisson's ratio will be
A tensile test is conducted for a metal wire which has a diameter of 4.5, the maximum recorded force was 3700N. Thus, UTS point is:
The results of a tensile test are shown in Table 1.5.2. The test was performed on a metal specimen with a circular cross section. The diameter was 3⁄8 inch and the gage length (the length over which the elongation is measured) was 2 inches. a. Use the data in Table 1.5.2 to produce a table of stress and strain values. b. Plot the stress–strain data and draw a best-fit curve. c. Compute the modulus of elasticity from the initial slope of the curve. d. Estimate the yield stress
