Question

If mass of 4 kg is attached to the end of a vertical wire of length 4 m with
a diameter 0.64 mm, the extension is 0.60 mm. Calculate the tensile stress
and strain?

Answer 1

Answer:

124 n/mm² , 15 x 10∧-5

Explanation:

tensile stress = 40N / π(0.32)²mm² = 124 n/mm²

tensile strain = 0.60 mm/ 4x1o³mm = 15 x 10∧-5
