Answer:
б₁ = 1.98 ksi
б₂ = 1.98 ksi
Explanation:
Calculating the component of stress acting at point A using circumferential stress equation, we have;
б₁ = p*r/t
= 90*11/0.25
= 3960 psi = 3.96 ksi
Calculating the component of stress acting at point A using longitudinal stress equation, we have;
б₂ = p*r/2*t
= 90*11 /2*0.25
= 1.98 ksi
Find attached of the volume element at point A.
