Which crucial innovation resulted when cast iron cannon production faced shattering?

💡 Explanation

Circumferential stress caused cast cannons to fracture; therefore, using wrought iron reinforcing bands applied hoop stress, limiting crack propagation because of the effect of autofrettage rather than relying solely on cast iron's tensile strength.

• Which systematic error affected 18th-century maritime sextant accuracy due to thermal expansion?
• Which constraint increases stress concentration impacting longship hulls amidst heavy Atlantic waves?
• Which outcome resulted during Roman siege warfare when defending city walls lacked counterweight trebuchets?
• Which obstacle hampered early Chinese gunpowder artillery scaling, caused by inconsistent blends?
• Which consequence results when differential expansion stresses rivets beyond yield strength in longships?
