The (G-E) diagram obtained in the tensile test performed on a metal sample with a
diameter of 16 mm is as follows. The loads at points A, B and C and the elongation measured
on l. 16 cm gauge length were determined as follows:

a) Calculate the proportionality limit, modulus of elasticity, tensile strength, maximum
uniform elongation, and contraction-elongation ratio of the metal.
b) Since the measured diameter of the metal at break is 12 mm, find the constriction ratio
and the actual stress at break.
The thin square plate shown is uniformly deformed such that €, = +1445 pE, E, = -674 uE, and y,y = +1260 urad. Determine the normal
