MoreJun 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:

MoreJun 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.

MorePlate #1, Steel Ball Roundness and Diameter Measurement Polylobular This is a ( bad ) example of the polar chart produced on the Talyrond. The inner poly lobular trace was made from a competitor's silicon nitride ball that was rated by them as a grade 10. The outer trace was made from a very good quality ball.

MoreBy 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.).

MoreIn 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.

MoreBall 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: $\text"Volume" = {4 ⋅ π ⋅ R^3 }/ 3$

MoreJan 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

MoreBall 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).

MoreR 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

MoreSo the largest probe a .001" crack can be detected by is a 0.010" ball-tip. A .002" crack will be detected by, at largest, a 0.020" ball-probe. And a .004" crack will allows at most a .040" ball probe. The spherical tips of all Ball Probes are made of tungsten carbide. Tungsten Carbide is one of the hardest, most wear-resistant materials known

MoreGauge 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.

MoreIn Rockwell’s method several types of penetrators are used: for soft materials, a small steel ball (HRB method) is used, for hard materials a diamond cone (HRC method). The diamond cone has a peak angle of 1200 and a radius of 0.2 mm round, while the diameter of the steel balls is 1/16″, 1/8″, 1/4″ and 1/2″.

MoreTo 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

MoreStokes' 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.

MoreRadius and button contact points are best for use on flat surfaces. Ball and wide ball contact points are for measuring indentations. They can also be used to measure flat surfaces. Flat, wide flat, and bell contact points are used for measuring convex surfaces. Needle, tapered, and knife contact points can probe the bottom of a groove or
