Question

A cylindrical silicon rod is pulled on both ends with a force of 22 mN. The rod is 5 mm long and 100µm in diameter. Find the stress and strain in the longitudinal direction of the rod.[Young’s Modulus of the cylindrical silicon rod= 140 GPa] Stress = 14×105 N/m2; Strain = 10 ×10-6 Stress = 28×105 N/m2; Strain = 20 ×10-6 Stress = 35×105 N/m2; Strain = 30 ×10-6 Stress = 20×105 N/m2; Strain = 28 ×10-6​
