Answer:
13.26 kip
Explanation:
Taking diameter of the rods as 0.75 in then considering that stress is Force per unit area
Force is a product of force and area
[tex]F=A\sigma[/tex] where [tex]\sigma[/tex] is stress
[tex]A=\pi \frac {d^{2}}{4}[/tex] and substituting this into the equation of force we get
[tex]F=\pi \frac {d^{2}}{4}[/tex]
Force, [tex]F=30*pi*\frac {0.75^{2}}{4}=13.26 kip[/tex]
