3. A 30-cm long, 12-mm diameter carbon steel rod was subjected to 15,5 kN of tension. Calculate (a) the stress and straîn in the rod, (b) the amount that it stretches, (c) its change in diameter, and (d) its stiffness (k=EA/L). (e) If the force was only 4.5 kN, by what amount would the rod have stretched?
