Answer:
The diameter of a square link is 0.0233 inch.
Explanation:
Given that,
Load = 27000 lbs
Modulus of elasticity [tex]E= 30\times10^{6}\ psi[/tex]
Working stress [tex]\sigma=7000\ psi[/tex]
length l = 55 in
We need to calculate the diameter of a square link
Using formula of stress
[tex] \sigma=\dfrac{Force}{Area}[/tex]
[tex]7000=\dfrac{27000}{\pi\times d\times L}[/tex]
Put the value into the formula
[tex]d=\dfrac{27000}{7000\times3.14\times55}[/tex]
[tex]d=0.0223\ inch[/tex]
Hence, The diameter of a square link is 0.0233 inch.
