Since the line is parallel, the same coefficients can be used for x and y. The constant on the right needs to change so that the given point will satisfy the equation.
... 5x - 4y = 5(-8) -4(2) = -40 -8 = -48
Your equation is
... 5x -4y = -48
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:
(
