Q6.A steel bar ABCD consists of three sections: AB is 20 mm diameter and 200 mm long, BC is 25 mm square and 400 mm long, and CD is of 12 mm diameter and compressive load which induces a stress of 30 MN/m2 on largest cross section. Determine the total decrease in length of the bar when the load is applied. For steel E= 210 GN/m2 200 mm long. The bar is subjected to axial

Q6.A steel bar ABCD consists of three sections: AB is 20 mm diameter
and 200 mm long, BC is 25 mm square and 400 mm long, and CD is
of 12 mm diameter and
200 mm long. The bar is subjected to axial
compressive load which induces a stress of 30 MN/m2 on largest
cross section. Determine the total decrease in length of the bar when
the load is applied. For steel E = 210 GN/m2
