Explain the purpose of the nitrogen charge in shock absorbers and struts.
What will be an ideal response?
During fast upward wheel movement on the compression stroke, excessive pressure in the lower oil chamber forces the base valve open and thus allows oil to flow through this valve to the reservoir. Nitrogen gas provides a compensating space for the oil that is displaced into the reservoir on the compression stroke and when the oil is heated. Since the gas exerts pressure on the oil, then cavitation, or foaming, of the oil is eliminated. When oil bubbles are eliminated in this way, the shock absorber provides continuous damping for wheel deflections as small as 0.078 inch (2.0 mm).

The Golden Gate bridge is maintained by 38 painters and 17 ironworkers (who replace corroding steel and rivets). If the painters get an average wage of $120,000 per year (with benefits) and the ironworkers get $150,000 per year, what is the capitalized cost today of all the future wages for bridge maintenance at an interest rate of 8% per year?

A new and unknown weight is weighed on the same scale that was used in Exercise 8, and the measurement is 127 µg above 1 kg. Using the information in Exercise 8, is it possible to come up with a more accurate measurement? If so, what is it? If not, explain why not.
