Chapter 12.1, Problem 12.2P
The value of g at any latitude
Which takes into account the effect of the rotation of the earth, as well as the fact that the earth is not truly spherical. Knowing that the weight of a silver bar has been officially designated as 5 Ib, determine to four significant figures, (a) the mass in slugs, (b) the weight in pounds at the latitudes of 0°, 45°, and 60°.

An engineer designing a light aircraft is trying to make an estimate of the diameter of the propeller needed. The design speed of the aircraft is 69m/s into still air and at this speed experience allows the engineer to assume a propeller efficiency of 88%. Other analysis shows that a thrust of 10906N must be supplied by the propeller to maintain this speed. Assuming a constant air density of 1.19 kg/m3 , determine the diameter of the ideal propeller in m to 1 decimal place.
At 45° latitude, the gravitational acceleration as a function of elevation z
above sea level is given by g=a-bz where a=9.807 ms ² and b=3.32×10 6
s ². Determine the height above sea level where the weight of an object will
decrease by 1 percent. Answer (29539 m)
