Delta 2 Rocket (US)
Mu-3SII Rocket (Japan)
The lead engineer on the new Starfinder rocket must determine the force in each member of the inter-stage truss structure. If the load is too high, the first-stage thrust will buckle the truss members.
What is known:
- The base ring radius is 1 m.
- The top ring radius is 0.75 m.
- The base and top ring are 1 m apart.
- The total thrust of the first-stage main engine is 2,400 kN (300 kN per joint).
