If an object that has a contact area of 0.05 m² creates a pressure of 34.570 kPa, what is its mass in kilograms?

Question

Quizplus · Accepted Answer

Using the equation: Pressure (kPa) = (Force / Area) / 1000 34.570 = ((mass × 9.81) / 0.05) / 1000 34.570 × 1000 = (mass × 9.81) / 0.05 34570 × 0.05 = mass × 9.81 1728.5 / 9.81 = mass mass = 176.2 kg Note: The "Force / Area" part of the equation is divided by 1000 to ensure that the resulting pressure is in units of kPa, rather than Pa or N/m² (i.e. 1 kPa = 1000 Pa or N/m²)
