# The outward force on one end of an air tank was calculated in Example 11.2. How is

## Question:

The outward force on one end of an air tank was calculated in Example 11.2. How is this force balanced? (The tank does not accelerate, so the force must be balanced.)

**Data given in Example 11.2**

An astronaut is working outside the International Space Station where the atmospheric pressure is essentially zero. The pressure gauge on her air tank reads 6.90 x 10^{6} Pa. What force does the air inside the tank exert on the flat end of the cylindrical tank, a disk 0.150 m in diameter?

**Strategy**

We can find the force exerted from the definition of pressure given inprovided we can find the area acted upon.
