How do you convert linear speed to angular speed?
To convert linear speed to angular speed, divide the linear speed by the radius of the rotating object. The formula for this relationship is: angular speed (ω) = linear speed (v) / radius (r). This will give you the angular speed in radians per second.
Why Do you need to balance the rear wheels?
If wheels aren't balanced they'll vibrate when they're rotating at speed. This can be unpleasant and can even increase wear on tires and suspension.
How is rpm related to speed?
More rpm means more speed, but the speed is also related to the diameter of the rotating object. The exact formula is: speed = angular speed x radius (assuming compatible units are used: for example, speed in meters/second, angular speed in expressed in radians/second, radius in meters).
What is the linear speed of a bicycle that has wheels with a 2m circumference when its wheels rotate at 1 revolution per second?
2 meter circumference rotating 1 revolution per second produces a linear speedof 2 meters per second.The question can be slightly more exciting if you give the diameter of the wheel,or even its radius, instead of its circumference.
What keeps water in a rotating bucket from falling out?
Centripetal force. The water wants to fall out due to gravity, but the speed of the rotating bucket cancels it out, creating an inward acceleration.. It is the same as why you don't fall out of an upside sown roller coaster. The speed has to such to cancel out gravity acceleration, where velocity squared divided by the radius of the rotating circle is the acceleration of gravity
What is the speed of low speed flywheel?
Generally, flywheels used for energy storage are divided into high-speed low-mass wheels rotating at 50,000 rpm and above and are typified by magnetic bearings and relatively small mass wheels (usually woven polymer fiber) measuring about 20-24 inches in diameter. Low-speed high-mass flywheels rotate at between 5-7,000 rpm and are typified by high mass solid wheels (steel and/or high-density alloys with diameters of several feet) supported by conventional tapered roller bearings.

What is the schwarzschild radius of earth?
The schwarzschild radius of the Earth is about 8.7 x 10 to the negative 3m. The schwarzschild radius is the radis of a sphere that is around a non-rotating blackhole. You find the Rs, or radis, by multiplying the gravitational constant(G), the mass(M), and two. You divide this by the speed of light(c) squared.
A Ferris wheel has a radius of 25 feet The wheel is rotating a 2 revolutions per minute Find the linear speed in feet per minute of the seat on this Ferris wheel?
1 revolution = 2PI radian. 2 revolutions = 4PI radian The angular speed of the Ferris wheel is 4PI radians . Multiply by the radius. The linear speed is 100PI feet per minute.
How does a change in radius effect linear velocity?
For circular motion, linear speed = angular speed (in radians) x radius. How the radius affects speed depends what assumptions you make about the problem. For example, if you assume the radius increases but the angular speed does not, then of course the linear speed will increase.
How do you convert angular speed to linear speed?
divide the linear speed by the radius
How much is the escape speed in the schwarzschild radius?
speed of sound
What is meant by Slip of an induction motor?
Slip is referred to as the difference between the speed of the rotor and the speed of the rotating magnetic field in the stator of the induction motor. Speed of the rotor=n(1-s) Speed of the rotating magnetic field= f/p
