Question
Transcribed Image Text:Part (b) Calculate the angular speed of the pedal sprocket Wn, in radians per second.
@p = ||
Transcribed Image Text:Problem 4: A bicyclist notes that the pedal sprocket has a radius of r, = 10.5 cm while the
wheel sprocket has a radius ofrw = 6.5 cm. The two sprockets are connected by a chain which
rotates without slipping. The bicycle wheel has a radius R = 66 cm. When pedaling the cyclist notes
that the pedal rotates at one revolution every t = 1.1 s. When pedaling, the wheel sprocket and the
wheel move at the same angular speed.
