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.
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?
Pressing the accelerator pedal can cause a change in velocity by increasing the speed of the vehicle even when maintaining a constant speed.
How do you measure instantaneous velocity?
Instantaneous velocity is typically measured by taking the derivative of an object's position function with respect to time. This derivative provides the object's velocity at a specific moment in time, giving the rate of change of position at that instant.
How do you change velocity in a car?
To increase velocity in a car, you can press the accelerator pedal to increase the speed. Conversely, to decrease velocity, you can either release the accelerator pedal to slow down gradually or apply the brakes to rapidly reduce speed. Maintaining a safe and controlled speed is essential for safe driving.
When a tractor moves with uniform velocity its heavier wheel rotates slowly than its lighter wheel why?
The heavier wheel has more inertia, which resists changes in motion. As a result, the heavier wheel rotates slower to maintain its uniform velocity with the tractor. The lighter wheel requires less force to rotate at the same speed due to its lower inertia.
How do I create the formula of velocity ratio of differential wheel and axle?
The velocity ratio of a differential wheel and axle system can be determined by taking the ratio of the angular velocities of the two wheels connected to the axle. This can be calculated using the formula: Velocity Ratio = (Angular velocity of wheel A) / (Angular velocity of wheel B) This ratio helps in understanding how the rotational speed of the wheels relates to each other when the axle is being driven.
Can a book have a consistent speed and a changing velocity?
No, a book cannot have a consistent speed and a changing velocity at the same time. Speed is a scalar quantity that only describes the magnitude of movement, while velocity is a vector quantity that includes both the magnitude and direction of movement. If the velocity is changing, then the speed must also be changing to reflect this variation.
What is the name for a wheel on a old phone?
It was called a "rotary dial".
Why are your velocity changes when you ride a ferris wheel even if the wheel turns at a constant speed?
Your velocity changes because velocity is a vector quantity that includes both speed and direction. When you ride a Ferris wheel, your direction changes as you move up and down, even though the wheel turns at a constant speed. This change in direction causes a change in your velocity.
