Q3 [4 marks] A plate of mild steel, 5 mm thick, 1000 mm long and 400 mm wide is stretched plastically 12% in the longitudinal direction. The characteristic stress-strain curve of the material is given by (σ = 500 Є 3 MPa). Assuming that the width is restrained from contracting by lateral end grips, calculate: a) final dimensions of the plate [1 mark] b) state of stress at the end of the stretching process [2 marks] c) final stretching load [1 mark] Assume no rolling pressure, and stress in the thickness direction = 0

For the stress-strain curves below, which statements are correct? Stress (MPa) 60 50 40 30 20 10 0 0 A B C. 1 2 3 4 Strain 5 6 7 8 a. The mechanical behavior shown in C is that of an elastomer with low elastic modulus b. While the deformation in polymer A is fully reversible until breakage, polymer B and C only display reversible deformation until 0.1X and 5x elongations respectively The mechanical behavior shown in B is that of an elastomer with low elasticity d. Polymer B and C have an elastic behavior whereas A has a plastic behavior e. The polymer with the necking behavior has the highest strength Of. The polymer with brittle nature is the one that possesses the highest elastic modulus
1.4-7 The data shown in the table below were obtained from a tensile test of high-strength steel. The test specimen had a diameter of 13 mm and a gage length of 50 mm (see figure for Prob. 1.4-3). At fracture, the elongation between the gage marks was 3.0 mm and the minimum diameter was 10.7 mm. Plot the conventional stress-strain curve for the steefor the steel and determine the proportional limit, modulus of elastics of elastic- ity (i.e., the slope of the initial part of the stress-strain,tress-strain curve), yield stress at 0.1% offset, ultimate stress, percent, elongation in 50 mm, and percent reduction in area.

Abrass rod is stress free at room temperature (20 Deg. C) It is then heated up, but prevented from lengthening at its ends by external forces. At what temperature does the stress in the rod reach -172 MPa? Assume the modulus of elasticity is 100 GPa, the linear coefficient of thermal expansion is 20 x 10%-6/Deg. <
