Consider a rotating disk cam and a translating roller follower with zero offset. Which one of the following pitch curves, parameterized by t, lying in the interval 0 to 2π, is associated with the maximum translation of the follower during one full rotation of the cam rotating about the center at (x, y) = (0, 0)?
A
x(t) = cos(t), y(t) = sin(t)
B
x(t) = cos(t), y(t) = 2sin(t)
C
x(t) = 1 + cos(t)/2, y(t) = 2sin(t)
D
x(t) = 1 + cos(t)/2, y(t) = sin(t)

Correct : c
