Question

Exercise 3: A metal wire 75 cm long and 0.13 cm in diameter stretches

0.035 cm when a load of 8 kg is hung on its end. Find the stress, strain and
Young's modulus for the materials of the wire.

Answer 1

A metal wire 75.0 cm long and 0.130 cm in diameter stretches 0.0350 cm when a load of 8.00 kg is hung on its end. Find the stress, the strain, and the Young’s modulus for the material of the wire.

Solution:

A metal wire 75.0 cm long and 0.130 cm in diameter stretches 0.0350 cm
