Overloading causes structural damage and failure.

Overloading causes structural damage and failure.

• A. Underloading
• B. Overloading
• C. Stall Impact
• D. Increased Performance

Answer: (B)

Exceeding the designed load capacity of a structure causes damage because the stresses in the material go beyond what it was built to safely handle. When loads exceed the allowable limit, the material can yield, crack, or buckle, and with repeated or dynamic overloading the fatigue life is shortened, making failure more likely. Underloading, in contrast, uses less than the design capacity and typically doesn’t cause damage. The other options describe aerodynamic or performance effects rather than the structural mechanism of damage, so they don’t explain why overloading leads to failure.
