A specimen of ductile cast iron having a rectangular cross

A specimen of ductile cast iron having a rectangular cross section of dimensions 4.8 mm ( 15.9 mm (3/16 in. ( 5/8 in.) is deformed in tension. Using the load-elongation data tabulated below, complete problems (a) through (f).

(a) Plot the data as engineering stress versus engineering strain.
(b) Compute the modulus of elasticity.
(c) Determine the yield strength at a strain offset of 0.002.
(d) Determine the tensile strength of this alloy.
(e) Compute the modulus of resilience.
(f) What is the ductility, in percentelongation?
