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.
