The drawing shows a chain-saw blade. The rotating sprocket tip at the end of the guide bar has a radius of 1400m. The linear speed of a chain link at the point A is 3.3m/s. Find the angular speed of the sprocket tip in rev/s.
To find the angular speed of the sprocket tip in rev/s, we need to convert the linear speed of a chain link at point A to angular speed.
The linear speed is given as 3.3 m/s. We know that the linear speed is equal to the radius multiplied by the angular speed.
Linear speed = Radius × Angular speed
Rearranging the formula to solve for angular speed:
Angular speed = Linear speed / Radius
Angular speed = 3.3 m/s / 1400 m
Angular speed = 0.00235 rev/s
Therefore, the angular speed of the sprocket tip is 0.00235 rev/s.
