QUESTION:
Problem 28E
Section 15.6 Elasticity
What hanging mass will increase the length of a 1.0-mm-diameter aluminum wire by 1.0%?
ANSWER:
Step 1 of 2
We need to find out what hanging mass will increase the length of the aluminum wire by 1 %.
Step 1 of 2
The weight is hanging on the wire so the pulling force on the wire,
\(F=m g\)
The tensile stress produced by this force is given by,
Tensile stress= \(\frac{F}{A}=\frac{m g}{A}\)
Consider Young's modu
