How does a rotating wheel have different velocities?
Although points at different distances from the center of a rotating wheel have different velocities, they all have the same angular velocity, so they all go around the same number of revolutions per minute, and the same number of radians per second.
What is the speed of a Norton Grinding Wheel?
All Norton grinding wheels are marked with a maximum operating speed in RPM. Most machines, and especially CNC machines, use Surface Feet Per Minute (SFPM) as an input, which requires operators to do the conversion.
How is rotational inertia related to vehicle speed?
In other words, we can describe the equivalent non-rotating mass of any rotating component as a function of its true static mass , its rotational inertia , and the ratio defined above. Note also that this relationship is independent of the vehicle speed , so the comparison is valid at any velocity, and is independent of vehicle power.
How does wheel housing affect the aerodynamic performance of a car?
There have been a number of studies of the aerodynamic performance of this area, which have shown that wheels and wheel-housing flows generate a significant part of the aerodynamic drag on a passenger car and can relate to as much as 25% of it.
How is vertical motion converted to horizontal motion?
Given the shaft moving up/down is moving on the Y-axis and the shaft moving left/right is moving on the X-axis. This crude diagram should explain things better. As the motor turns Shaft A upwards it then turns Shaft C. Shaft C then moves Shaft B left and right
For a point on the top of a tire, the two velocities are in the same direction, so the total velocity at the top of a tire is twice the linear velocity of the car; for a point at the bottom of a tire, the two velocities are in opposite directions, so the total velocity is zero there.
How are rotational variables related to straight line motion?
Any equation dealing with rotation can be found from its straight-line motion equivalent by substituting the corresponding rotational variables. The straight-line motion kinematics equations apply for constant acceleration, so it follows that the rotational kinematics equations apply when the angular acceleration is constant.
