4. Backup Slide - Strength
Strength Calculation
σ = F/A (σ, stress; F, force; A, area)
F = g*(gond_weight + GLOW) (g, m/s2; gond_weight, mass of gondola without the base; GLOW, gross liftoff weight)
A = area of gondola base
Max. Strength of Aluminum = 455 MPa
Strength of Gondola
200 g: 56,301 Pa
1 kg: 32,704 Pa
5 kg: 75,479 Pa
Conclusion: Gondola Will Hold!
