Question
A diagonal aluminum alloy tension rod of diameter d and initial length l is used in a rectangularframe to prevent collapse. The rod can safely support a tensile stress of sallow. If d 5 0.5 in,l 5 8 ft, and sallow 5 20 kpsi, determine how much the rod must be stretched to develop thisallowable stress.

Answer:
The stretched length is 0.18816 in.
Explanation:
Given that,
Distance = 0.5 in
length = 8 ft
Tensile stress = 20 kpsi
We need to calculate the stretched length
Using formula of length
Where,
= Tensile stress
L = length
E = young’s modulus of aluminum
Put the value into the formula
Hence, The stretched length is 0.18816 in.
