Round Tube Beams Deflection Calculation  

MI for Solid Round Beams = (pi * (OD^{4}  ID^{4})) / 64
Deflection = (length^{3} * force) / (3 * E * MI)
Bending Stress = (force * length) / (MI / (0.5 * height))
Where,
MI = Moment of Inertia
E = Modulas of Elasticity in psi
Solution:
Apply Formula:
MI for Solid Round Beams = (pi * (OD^{4}  ID^{4})) / 64
Deflection = (length^{3} * force) / (3 * E * MI)
Bending Stress = (force * length) / (MI / (0.5 * height))
Deflection = 0.000006111549814728781 (Inches)
Bending Stress = 6.111549814728781 (PSI)
