Question

A steel bar 600mm2

cross-sectional area is carrying loads as shown in fig.

Determine the stresses in each part and total elongation of the bar. Take

E = 210 GPa. & length of each part is 1m.



​

Answer 1

Answer:

1. A copper bar shown in figure is subjected to a tensile load of 30 KN. Determine elongation of the bar if E=100GPa. Also find maximum stress induced.

2. A copper bar 900mm long and circular in section . It consists of 200mm long bar of 40 mm diameter,500 mm long bar of 15 mm diameter and 200mm long bar of 30mm diameter. If the bar is subjected to a tensile load of 60kN,Find the total extension of the bar.Take E=100GPa
