Question

If the strain in a wire is not more than 1/1000 and y = 2 × 10^11 the maximum weight hung from wire is

Answer 1

Hii friend,

You have given incomplete question.

We also need cross sectional area of wire to calculate maximum load applied.

Let's calculate maximum stress.

# Solution-

Young modulus = stress/strain

strain=1/1000

stress=F/A

stress = strain × young modulus

stress = 1/1000 × 2×10^11

stress = 2×10^8 N/sq.m

F = 2×10^8 × A N.

Maximum stress applied can be 2×10^8 N/sq.m.

Maximum load 2×10^8 × A N.

Hope that cleared your problem...
