1.	A structural steel rod has a radius 10 mm and a larngth of 2.0 m.A force of 10 KN stretches it along its length. Calculate (a) Stress (b) Elongation and (c ) Strain on the rod. Young's modulus of structural steel is 2.0 xx 10 ^(11) Nm ^(-2) .
Answer» Solution :Stress`=3.18 xx 10 ^(7) NM ^(-2),` Elongation `Delta L = 1.59 xx 10 ^(-4) M,` Strain `= 0.016 %`
