The following data were collected from a 0.4-in.-deameter test specimen of polyvinyl chloride (l0 = 2.0 in.):

After fracture, the total length was 2,09 in., and the diameter was 0.393 in. Plot the engineering stress-strain curve and calculate
(a) The 0.2% offset yield strength;
(b) The tensile strength:
(c) The modulus of elasticity:
(d) The % elongation;
(e) The % reduction in area;
(f) The engineering stress at fracture;
(g) The true stress at necking; and
(h) The modulus of resilience.
