The angular velocity of the shaft is 21 radians per second. determine the number of its full revolutions per minute.

Let’s calculate the angular velocity in radians per minute. Since there are 60 seconds in a minute, then:
21 * 60 = 1260 (glad).
1 radian is approximately 57.3 °, one full revolution is 360 °, therefore, in a minute, the shaft makes:
1260 * 57.3 / 360 = 200.55 (revolutions)
This means that the shaft makes 200 full revolutions per minute.
Answer: 200 full revolutions.
