Definition of the Radian One radian is the angle subtended at the center of a circle by an arc length s equal to the radius R of the circle. s R s R 1 rad = = 57.3 0 R
Example 1: A rope is wrapped many times around a drum of radius 50 cm. . How many revolutions of the drum are required to raise a bucket to a height of 20 m? m s R 20 m 0.50 m Now, 1 rev = 22 rad = 40 rad R 1 rev 2 rad 40 rad h = 20 m = 6.37 rev
