**How do you calculate revolutions per minute? Yahoo Answers**

Trigonometry section 5.4 – Radians, Arc Length, Linear Speed, and Angular Speed Variables: ( ) ( ) to get Dimensional analysis conversion factors: Steps to Solve: 1. Identify what is given and what you are trying to find; identify all variables and associated units. 2. Determine which equation relates the known and unknown variables.... The angular speed of the carousel is 4.3 revolutions per minute. in Calculate the linear speed of each rider in feet per second? Who is traveling at a faster rate? Why? (Round answers to the nearest tenth)

**Pre calculus Angular speed/ Linear speed Stack Exchange**

The required pulses per revolution is calculated by dividing the lead of the screw by the linear resolution needed for the application.... In the mid-20th Century, people were using turntables to spin records at 45 revolutions per minute. CDs spin at an angular speed of 500 rpm when read from the center and 200 rpm when read near the circumference. Besides having an angular velocity, the CD also has a constant linear velocity (CLV). The CLV of a CD has been standardized by Philips at 1.2 to 1.4 m/s.

**Given initial angular velocity of wheel find revolutions**

However sometimes we will give the result in other layman’s terms, such as revolutions We also can find the angular velocity and the linear velocity at the equator of a planet given that we know the radius of the planet r and the time that it takes for the planet to make one ( 360!) rotation on its axis. (Note: One 360! rotation on the axis is not the same as the actual length of a day... The required pulses per revolution is calculated by dividing the lead of the screw by the linear resolution needed for the application.

(Round answers to the nearest tenth)... 18/01/2010 · 1. Find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s. r = 1 meter, s = 300 centimeters From what I did in the past THETA = S/R where in this case would equal 300/1 = 300 radians however I got it wrong, not sure what I'm missing.

## How To Find Linear Speed With Revolutions

### 3/04/2014 · A truck with 54 inch diameter wheels is traveling at 45 mi/hr. Find the angular speed of the wheels in rad/min. How many revolutions per minute do the wheels make?

- RPM is used with many key parameters such as diameter, mass and torque in fixed engineering formulas to calculate horsepower, linear velocity, gear ratios and tangential velocity. Conversely, a number of measurements can be made in any given system to calculate RPM. Since there is no one formula, several examples are provided below.
- Linear Speed Example #2 A wheel in a large machine has a radius of 2500000 in and rotates at 5000000 revolutions a sec. How fast is a point on the circumference of the wheel in ft/min?
- In this case, the drive converts the encoder output to linear speed s in feet per second as follows: where fp is pulse frequency in hertz, R is resolution in pulses per revolution. Linear speed …
- Find the angular speed of the car tire in revolutions per second when it is traveling 70 mph. Find the angular speed at 80 mph. The tires on a car are 15 inches. Find the linear speed of …
