Question

A mild steel bar of square cross-section 10 mm x 10 mm is subjected to the forces as shown in Fig. 2.28. Calculate the change in the length of the bar. Take E = 200 kN/mm2. (Ans. 0.01 mm (increase)) 1 KN 4 KN 6 KN 3 KN 300 mm -200 mm K 100> mm ​

Answer 1

Explanation:

Given data, P = 200 N, A = 10 mm × 10 mm = 100 mm2

E = 200 GPa = 200 × 103 MPa
