Pressure & Moments

Army tank tracks are useful for travelling through the mud because..

• they decrease the force the vehicle exerts on the ground
• they increase the force the vehicle exerts on the ground
• they decrease the pressure the vehicle exerts on the ground
• they increase the pressure the vehicle exerts on the ground

Which of these animals would probably cause the greatest pressure on the ground?

• A fat cow with big feet
• A fat cow with small feet
•  A calf with big feet
• A calf with small feet

The amount of force pushing on an area is the definition of....

• Fluid
• Viscosity
• Barometer
• Pressure

Which of the statements is true?

• The bottom of the boot exerts more pressure than the shoe as a result of an increase in surface area.
• The bottom of the shoe exerts more pressure than the boot as a result of an decrease in surface area.

Look at the pressure triangle. How do we calculate the area?

• f ÷ a
• f x p
• p x f
• f ÷ p
