What equation defines pressure?

Pressure is defined as the force exerted per unit area. This relationship is mathematically expressed by the equation P = F ÷ A, where P represents pressure, F is the force applied, and A is the area over which the force is distributed. This equation highlights that as the force increases, pressure also increases, provided the area remains constant. Conversely, if the area increases while the force remains the same, the pressure will decrease.

Understanding this concept is essential for various applications in building maintenance, such as ensuring that materials and structures can withstand the forces placed upon them without failing. The pressure equation is foundational in fields like hydraulics, ventilation, and even structural engineering, where pressure calculations are critical for safety and effectiveness.
