A commercial driver evaluates various wheel and tire assembly components during a safety inspection. Which hazard or mechanical consequence corresponds to each observed wheel defect? Match each inspection finding on the left with its correct safety implication on the right.
- Rust streaks radiating outward from wheel lug nutsSignals loose hardware that can cause wheel instability or detachment
- Dual tires mounted on the same axle making physical contactCauses excessive friction and heat buildup between sidewalls, risking blowouts or fires
- Missing or broken valve stem capsAllows dirt and moisture to contaminate the internal valve core, causing gradual air loss
- Welded repairs visible on a steel wheel rimWeakens structural rim integrity and violates commercial safety regulations
Cevap
Rust streaks match with signaling loose hardware and wheel detachment risk; touching dual tires match with excessive friction and fire risk; missing valve caps match with dirt contamination and air loss; and welded rim repairs match with illegal structural weakening.
Each defect maps directly to its specific mechanical failure mode: rust trails indicate loose lug nuts, dual tire contact generates friction and tire fires, missing valve caps allow debris to ruin valve cores causing air leakage, and welded rims represent illegal and dangerous structural compromises.
