Question

A rod 150 cm long and of diameter 2.0 cm is subjected to an axial pull of 20 kn. if the modulus of elasticity of the material of the rod is 2 x 105 n/mm2 ; determine: (i) the stress, (ii) the strain, and (iii) the elongation of the, rod

Answer 1

Answer:

i 105.2 n

ii 105 n

iii 105.22 n + 20 kn=105.2220 mm

Explanation: the i is the stress

the ii is the strain

the iii is the elongation
