Physics · Elasticity
One end of a steel wire is fixed to the ceiling of an elevator moving up with an acceleration of 2 m/s2 and a load of 10 kg hangs from the other end. If the cross-sectional area of the wire is 2 cm2, then the longitudinal strain in the wire will be (Take g = 10 m/s2 and Young's modulus Y = 2.0 × 1011 N/m2):
