### How to accurately measure the Diameter of a Ball

Jun 02, 2019· Once you’ve divided your circumference by 3.14, you’ll successfully have calculated the diameter of your ball. As an example, if you measure a yoga ball and its circumference measures 67.71 inches, the diameter of the yoga ball which you’re measuring will be 21.65 inches. How to measure the diameter of a circle:

### How can I find the mass of a steel ball given its radius

Jun 27, 2008· The radius of the steel ball is r = 2cm = 0.02m and its specific heat is c = 0.486kJ/kgK Analyzing the units of these given values, I thought simple unit analysis would work. For example, 1/c would give units of kgK/kJ. The volume of the ball is v = (4/3)pi(r)^3 which has units of m^3. I'm having a difficult time trying to relate these things and manipulate them to just get the mass of this ball.

### Bal-tec What is a Sphere?

By applying a thin coating of prussian blue to the raceway of a ball bearing and drawing a ball across it, the ball radius to the bearing radius can be measured, see (Figure # 18.). Measuring the internal spherical diameter of rod end bearings is accomplished using two ball plug gages, each with two flats ground on the balls, see (Figure # 19.).

### Solved: In A Certain Experiment A Student Measured The Rad

In a certain experiment a student measured the radius and volume of a steel ball 9 times. The volume measurements were seperate measurements from the radius measurements (not calculated from the radius values). Remember to write your answers with the number of significant figures determined by the relevant uncertainty in your measurement.

### Bal-tec Ball Weight and Density

Ball Weight and Density How much will a ball of a given diameter in a certain material weigh? The answer is calculated by multiplying the volume of the ball by the density of the material. $\text"Weight" = \text"Volume" ⋅ \text"Density"$ For example, calculate the weight of a two inch diameter lead ball: $\text"Volume" = {4 ⋅ π ⋅ R^3 }/ 3$

### Measuring Taper with Gage Balls Practical Machinist

Jan 27, 2017· R = radius of large ball minus the radius of the small ball (making sure we have a way to get that ball out!) and using a depth gage measure the distance from a reference surface to the ball as l (small L). This is roughly 5 or 6 gauge aluminum or steel. Let's assume you can get gauge balls of the right size. For the sake of argument

### Ball COR Sports Science Laboratory Washington State

Ball COR. The coefficient of restitution (or COR) is a measure of the energy that is lost during impact. Balls with higher COR will be more lively in play. While it is close to 0.5 for most balls, it can range from 1 (no energy lost) to 0 (all energy lost).

### Stokes' law Wikipedia

R is the radius of the spherical object; v is the flow velocity relative to the object. In SI units, F d is given in newtons (= kg m s −2), μ in Pa·s (= kg m −1 s −1), R in meters, and v in m/s. Stokes' law makes the following assumptions for the behavior of a particle in a fluid: Laminar flow; Spherical particles; Homogeneous (uniform

### Gauge block Wikipedia

Gauge blocks (also known as gage blocks, Johansson gauges, slip gauges, or Jo blocks) are a system for producing precision lengths.The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness. Gauge blocks come in sets of blocks with a range of standard lengths.

### Spherometer Wikipedia

To measure the radius of a sphere—e.g. the curvature of a lens—the spherometer is leveled and read, then placed on the sphere, adjusted until the four points exert equal pressure, and read again. The difference gives the thickness of that portion of the sphere cut off by a plane passing through the three feet. this was etided

### Viscometer Wikipedia

Stokes' law is the basis of the falling-sphere viscometer, in which the fluid is stationary in a vertical glass tube. A sphere of known size and density is allowed to descend through the liquid. If correctly selected, it reaches terminal velocity, which can be measured by the time it takes to pass two marks on the tube.Electronic sensing can be used for opaque fluids.
