Question

1) A cylindrical silicon rod is pulled on both ends with a force of 22 mN. The rod is 5 mm long and 100um in diameter. Find the stress and strain in. 2
the longitudinal direction of the rod.
[Young's Modulus of the cylindrical silicon rod= 140 GPa)
Stress = 14:10
N/m2: Strain
= 10 %100
Stress = 28 10 N/m2. Strain = 20 10 9
O Stress = 35:10 N/m? Strain = 30 106
Stress = 20x105 N/m Sirain = 28 x108​
