Question 1 Report
A copper wire was subjected to a tensile stress of 7.7 x 107 x 10 Nm-2. calculate strain of the wire. [young modules = 1.1 x 1011 Nm-2]
Answer Details
Young modules = Tensile stressTensile strain Tensile stress Tensile strain
= 1.1×1011=7.7×107Tensile Strain 1.1 × 10 1 1 = 7.7 × 10 7 Tensile Strain
∴ Tensile strain = 7.7×1071.1×1011 7.7 × 10 7 1.1 × 10 1 1
= 7.0×107−11=7.0×10−4
