Answer:
Both rod have the same tensile stress
Explanation:
Given information,
The weight first rod, = 1000 N
The length of first rod, = 2.0 m
The weight second rod, = 500 N
The length of second rod, = 1.0 m
The equation of tensile stress, σ =
where
σ = tensile stress (N/ or Pa)
F = Force (N)
A = Area (N/ or Pa)
so
σ1 = , A = 2πl
=
= N/
now calculate σ2
σ2 =
=
= N/
σ1/σ2 = /
σ1/σ2 = 1
σ1 = σ2
Hence, the tensile stress of first and second rod are the same.
