A jet transport aircraft, with pressurized cabin, cruises at 11 km altitude. The cabin temperature and pressure initially are at 25°C and equivalent to 2.5 km altitude. The interior volume of the cabin is 25 m 3 . Air escapes through a small hole with effective flow area of 0.002 m 2 . Calculate the time required for the cabin pressure to decrease by 40 percent. Plot the cabin pressure as a function of time.

The net force exerted on the piston by the exploding fuel-air mixture
and friction is 5 kN to the left. A clockwise couple M = 200 N-m acts on the crank AB.
The moment of inertia of the crank about A is 0.0003 kg-m2
. The mass of the
connecting rod BC is 0.36 kg, and its center of mass is 40 mm from B on the line from B
to C. The connecting rod’s moment of inertia about its center of mass is 0.0004 kg-m2
.
The mass of the piston is 4.6 kg. The crank AB has a counterclockwise angular velocity
of 2000 rpm at the instant shown. Neglect the gravitational forces on the crank,
connecting rod, and piston – they still have mass, just don’t include weight on the FBDs.
What is the piston’s acceleration?
