1. These phenomena are explained by concepts like pressure distribution, surface area, and force application. Camels' wide feet, tank tracks, and wide tires reduce ground pressure, while sharp cutting tools concentrate force on a small area for efficient cutting.

  2. The effects of forces of the same magnitude differ due to pressure, which is the force applied per unit area. A larger area distributes the force, reducing pressure and impact, while a smaller area concentrates the force, increasing pressure and impact. This principle explains variations in pressureRead more

    The effects of forces of the same magnitude differ due to pressure, which is the force applied per unit area. A larger area distributes the force, reducing pressure and impact, while a smaller area concentrates the force, increasing pressure and impact. This principle explains variations in pressure effects on different surfaces.

  3. The area of contact affects thrust impact on loose sand by distributing weight over a larger surface when lying down, reducing pressure and preventing sinking. Standing concentrates weight on a smaller area, increasing pressure and causing deeper sinking. Hence, lying down minimizes impact comparedRead more
