Show Easy to t Demonstrate 1 The problem of the revolution re ot of a R J t il a be explained d b by the ther fact that the top Is moving mooring forward forwald In the j II direction In which the he vehicle Is pro pro- I grossing white while the tho bottom Is moving backward or 01 In an an opposite direction I To o demonstrate this in a practical way take n it a coin mark points at the top and botton bolton as A and B. B Make 1 a n mark at atthe atthe attie the tie starting point directly beneath A I t and md 1 n Ii upon whatever r surface the coin eom I Is to tobe be rolled Roll Roll HoU the coin forward forwar 1 l la a quarter revolution It It will ill be c seen J l ltha that hunt t A m moves Y s upon upon a radius equal to t the diameter of or the circle nn and lI by actual actual ac ac- ac- ac measurement A has hns moved a i greater distance V and described n a greater curve curc than B.
