If a ferris wheel is rotating at constant speed is it moving at a constant velocity?
No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
How to Convert revolution per minute to metres per minute?
You cannot. Revolutions per minute are a measure of angular velocity whereas metres per minute are a measure of linear velocity. There is no simple way to convert from one to the other. For example, at any given rpm, a point on the rim of a wheel is moving much faster than a point near the hub. You need the distance of a point from the axis of revolution (in metres) to convert angular speed to linear speed. If the distance from the centre is r metres then the point moves through 2*pi*r metres every revolution. ie 1 rpm = 2*pi*r linear metres per minute.
True or false the linear velocity of a point that is 1 ft from the center of a wheel rotating at 1 rev per sec is 2 pie ft per sec?
If this is a homework assignment, you really should consider trying it by yourself first, otherwise the value of the reinforcement of the lesson by the act of doing the homework will be lost on you.The circumference of a circle of radius 1 is 2 pi, therefore, a point on that circle rotating at a speed of 1 revolution per second has a linear (tangent) velocity of 2 pi feet per second.
A 12 inch grinding wheel has a surface speed of a mile a minute. What is its revolutions per minute?
A wheel with a diameter of 12 inches will have an angular speed of 560.2 revs per minute.
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.
How do you measure instantaneous velocity?
You can transform linear velocity into rotational velocity with a rolling wheel. Rotational velocity can be measured inside a gravity field because of generated centrifugal force. When you suspend your arms freely while rotating, the angle between your body and your arm is a measure for the rotational speed.
What are steering gear box for?
To turn the rotary motion of the steering wheel into a linear (back & forth) motion that can turn the wheels.
If a ferris wheel is rotating at constant speed is it moving at a constant velocity?
No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
Mechanism to transfer linear to rotary motion?
"Think of a simple single cylinder engine....crankshaft goes round & round,piston goes up & down,connecting rod keeps the two tied together...wa la!" This type of linear motion is known as reciprocating motion, where the linear motion is a repetitive up and down, or back and forth action. The linear motion velocity of a wheel and crank system is not uniform and conforms to a sinusodial curve, i.e. it is slowest at the 0º and 180º positions and fastest at the 90º position. To get uniform linear motion from uniform rotary motion, you can use a threaded shaft and thread follower arrangement, or a rack and pinion. btw, it's "voila!".
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.
What control on a car can cause a change in velocity at constant speed?
The steering wheel can change the car's direction of motion, without changing speed.
Can a book have a consistent speed and a changing velocity?
Yes it can. Especially if it's riding the periphery of a roulette wheel, glued to the rim of a car's tire, or spinning around your head on the end of a yo-yo string. Velocity consists of speed and direction. If the direction of motion is changing then the velocity is changing, even if the speed is constant.
What is the name for a wheel on a old phone?
It was called a "rotary dial".
Why does steering wheel shake at high speed?
im guessing it has something to do with velocity and road conditions. yet again, if i'd imagine that a steering wheel shouldn't shake.... that can't be good.
How do you change velocity in a car?
The accelerator is one: to increase velocity, push the pedal down, to decrease, lift your foot off. The brake is another, apply the brake and velocity will decrease. also the steering wheel affects it. The gas pedal, the brake pedal, and the steering wheel all do.
Does it matter how big the wheel is when measuring RPMs?
No. A revolution is a revolution is a revolution. Two wheels of different diameters can have the same rotational velocity (in rpm) or angular velocity (in radians per second or degrees per second). Mark the outer edge of the wheel, and count the number of full revolutions it makes in one second. But I have a feeling your question is poorly worded. You should realize that a smaller wheel will rotate faster than a larger one for a given linear velocity. For example, if you are riding a bicycle, say, with a small wheel on the front and a large one on the back, the smaller front wheel will need to rotate faster -- that is, it's angular velocity will be greater -- than the larger back wheel.
How to Convert revolution per minute to metres per minute?
You cannot. Revolutions per minute are a measure of angular velocity whereas metres per minute are a measure of linear velocity. There is no simple way to convert from one to the other. For example, at any given rpm, a point on the rim of a wheel is moving much faster than a point near the hub. You need the distance of a point from the axis of revolution (in metres) to convert angular speed to linear speed. If the distance from the centre is r metres then the point moves through 2*pi*r metres every revolution. ie 1 rpm = 2*pi*r linear metres per minute.
