The rotational speed of the motor pulley is n = 120r / min. the distance between a point on the pulley and the axle is 10cm. Calculate the rotational frequency, periodic angular velocity and linear velocity of this point?

The rotational speed of the motor pulley is n = 120r / min. the distance between a point on the pulley and the axle is 10cm. Calculate the rotational frequency, periodic angular velocity and linear velocity of this point?

Rotation frequency = 120 / 60 = 2
Period = 1 / 2
Angular velocity = 4 Π / S
Linear velocity = 4 Π r = 4 * 3.14 * 0.1 = 1.256m/s
