Which outcome occurs when gunpowder, used in early Chinese signaling rockets, exceeds its pressure design limit?

💡 Explanation

When gunpowder exceeds its pressure tolerance, stress concentration leads to catastrophic casing failure because the hoop stress overcomes material strength, creating rapid crack propagation rather than controlled thrusting; therefore casing fails, rather than stable remains maintaining flight.
