Pressure acting on a surface of area 100cm2 when the force of 1000N is acting normally on it |
|
Answer» Answer: The relationship between pressure and force is as follows: Pressure = Force / Area. Strictly speaking a kg/cm² is actually kgf/cm². So for a pressure of 1kgf/cm² to PRODUCE a 2kg force the SURFACE area WOULD be calculated as follows: Area = Force / Pressure = 2 kgf / 1 kgf/cm² = 2 cm². |
