1.	A structural steel rod has a radius 10 mm and a length of 2.0 m . A force 100 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 ^(8) NM ^(-2) ,` Elongation `DELTA L = 3.18 xx 10 ^(-3) m, ` STRAIN `= 0.16%`
