Answer:
15
Step-by-step explanation:
Answer:
Angular velocity:
(
)
Linear velocity:
(
)
Step-by-step explanation:
The gear experiments a pure rotation with axis passing through its center, the angular (
), in radians per second, and linear velocities (
), in inches per second, of a point on the outer edge of the element are, respectively:
(1)
(2)
Where:
- Rotation rate, in revolutions per minute.
- Radius of the gear, in inches.
If we know that
and
, then the linear and angular velocities of the gear are, respectively:

(
)
