The geometric implications of a V-flat drive are interesting.
(a) If the earth’s equator was an inextensible string, snug to the spherical earth, and you spliced 6 ft of string into the equatorial cord and arranged it to be concentric to the equator, how far off the ground is the string?
(b) Using the solution to part a, formulate the modifications to the expressions for mG , θd and θD , Lp , and C.
(c) As a result of this exercise, how would you revise your solution to part b of Prob. 17–20?
