1200 Mechanical principals
1200 Mechanical Principles: The Foundation of Engineering Mechanical principles are the fundamental laws that govern the behavior of forces, motion, and energy in mechanical systems. These principles are essential in designing and operating machines, structures, and mechanical components. Key Mechanical Principles: 1. Newton’s Laws of Motion First Law (Inertia): An object remains at rest or in uniform motion unless acted upon by an external force. Second Law (Force and Acceleration): Force equals mass times acceleration (F = ma). Third Law (Action and Reaction): Every action has an equal and opposite reaction. 2. Laws of Thermodynamics First Law: Energy cannot be created or destroyed, only transferred or converted. Second Law: Entropy always increases in an isolated system. Third Law: As temperature approaches absolute zero, entropy approaches a constant. 3. Friction and Wear Static Friction: Resistance before movement occurs. Kinetic Friction: Resistance when objects are...
