1. An oxygen bottle was serviced to the manufactures recommended pressure of 1487 psig at an outside temperature of 50 degrees Fahrenheit. The aircraft flew to the desert where the outside temperature indicated 102 degrees Fahrenheit. What will be the pressure of the oxygen be inside this container when it reached 102^o F? Give your answer in gage pressure and assume a constant volume.

2. In a hydraulic system where the force applied to piston A1 is 53.2pounds & theweight being lifted at A2 is 95.7 pounds, how far will A2 be raisedif A1is depressed 14.8 inches?

3. If the final pressure of an enclosed gas is 13.6 psig after its volume is increased from 24 cubic inches to 96 cubic inches without a change in temperature, what was its initial pressure in psig?

Calculate your answer to 2 decimal places.

4. In a hydraulic system where the area of piston A1 is 4.6in.² &the area of A2is 12.4in.² ,how much weight can be lifted at A2if a force of 54pounds is applied at A1?

5. In a hydraulic system where the area of piston A1 is 3.4 in.²& the area of A2is 10.5 in.², how far must A1be depressed to raise A2 3.6 inches?

6. In a hydraulic system where the area of piston A1 is 5.8in.² &the area of A2is 11.8in.² ,how much force needs to be applied to A1to lift 190pounds at A2?

7. In the hydraulic system pictured with a piston of area 9.5 in.²and a piston rod extending outside of the system with area 2.6 in.², what is the resultant force acting to force the piston to the right if the system pressure is 54 lbs. per in.²?
