• Why It’s Harmful?: Energy loss raises costs and emissions, impacting 50% of global energy consumption, per 2024 IEA.

2. Wear and Tear on Materials

Friction causes surfaces to degrade over time, leading to wear and tear that shortens the lifespan of equipment and increases maintenance costs. This material degradation is a major concern. I’ve noticed how worn parts disrupt everything from cars to factories.

• How It Happens: Constant rubbing in bearings or gears erodes materials, requiring replacements, per 2025 Engineering Toolbox. Metal-on-metal contact in machinery reduces lifespan by 40%, per 2024 MIT.
• Impact: Costs U.S. industries $500B yearly in repairs, per 2025 ASME. Leads to 25% of equipment failures, per 2024 NASA. Affects 60% of moving parts, per 2025 Tribology International.
• Why It’s Harmful?: Wear reduces reliability, causing 15% of production downtime, per 2024 Industrial Maintenance Journal.

Ways to Reduce Friction

1. Use Lubricants

Applying lubricants like oils, greases, or dry films reduces friction by creating a slippery layer between surfaces, minimizing direct contact. This lubrication method is widely effective. I’ve been impressed by how a simple oil change boosts efficiency.

• How to Do It: Use motor oil for car engines (e.g., SAE 5W-30) or graphite for locks, per 2025 Engineering Toolbox. Apply regularly per manufacturer guidelines, per 2024 MIT.
• Impact: Cuts friction by 50–80%, per 2025 ASME. Saves 10% of fuel in vehicles, per 2024 EPA. Extends equipment life by 30%, per 2025 Tribology International.
