A gear of radius 1m turns counterclockwise and drives a larger gear of radius 4m. Both gears have their axes along the horizontal.

a) In which direction is the larger gear turning?
b) If the period of the smaller gear is 2s, what is the period of the larger gear?
c) In a table, record convenient intervals for reach gear, to show the vertical displacement, d, of the point where the two gears first touched. Begin the table at 0s and end it at 24s.
e) What is the displacement of the drive wheel when the large wheel first has a displacement of 2m?
