Question 3

Pros and cons of 3D printing

Answer 3

Pros- Speed, reduced cost, increased design freedom

Cons- Material and size limitations, Questionable accuracy

Question 4

When wings bend upwards what happens?

Answer 4

Deformation leads to σ. Compression and shear in upper wing panels, tension and shear in lower wing panels

Question 5

Positions and their relative loads and criteria

Answer 5

Landing- Undercarriage + front landing gear- Static ground load

Fuselage bending- Top of fuselage- Tensile/fatigue loads

-Side of fuselage-Shear/fatigue loads
