I have been given an experiment to perform, whereby I drop steel ball bearings into a glass measuring cylinder, and time how long it takes for the ball bearing to fall a set distance. From this I should be able to work out the viscosity coeffienct of the glycerol. I have been given this sum to work with: [itex]2g/9(p-o)r^2/v [/itex] Whereby :

So 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 ...

How to measure diameter of a ball: In order to calculate the diameter of a ball use a tape measure to measure the circumference of your ball. To measure the circumference of your ball wrap your tape measure around your ball once. Once you've written down the number of your ball's circumference divide the number which you have by pi.

Measure the radius of the ball-bearing r and determine the radius of curvature of the surface R using the spherometer as described in Appendix B. Note: please do this on the concave spherical surface (rather than the convex one on page 1.10) – otherwise you may get the wrong answer. Ensure you include the errors on each value and make

To a first approximation, a tennis ball is a sphere. The volume of a sphere is V = 4/3 π r3, where r is the radius of the sphere. So measure the diameter of the tennis ball, divide by 2 ...

73. A group of students is investigating whether copper is a better thermal conductor than steel. The students take a copper wire and a steel wire of the same length and diameter. They put equal lengths of wax on one end of each wire and dip the other end into a beaker of hot water. The length of wax left on the wires after 10 minutes is shown.

The diamond cone is solely used for tempered or hardened steel and hard metal. It is not recommendable for steel with a solidity below 785 N/mm2 (20 HRC, 230 HB/30). The steel ball penetrator is used for softer materials. The softer the material, the larger should be the diameter of the ball and / or the smaller should be the total test load.

Next, select the steel ball at your lab table for measurement. Place the jaws of the digital caliper in contact with each other and once again zero the readout. Measure and record, in millimeters, the diameter of the steel ball with the caliper in 8 different orientations. Enter this data in Table 2.

A student measured the diameter of a small steel ball using a screw gauge of least count 0.001 cm. The main scale reading is 5 mm and zero of circular scale division coincides with 25 divisions above the reference level. If screw gauge has a zero error of −0.004 cm, the correct diameter of the ball is? A 0.053 cm B 0.521 cm C 0.529 cm D 0.525 cm

Enter the radius of the sphere. For size 5 soccer ball radius should be equal to 4.3-4.5 in, let's take 4.4 in. The sphere volume appeared, as the circumference. They are equal to 357 cu in and 27.6 in. Assume that for the basketball we don't know the radius. Type in the circumference instead. For basketball size 7 the typical one is 29.5 in.

A small steel ball of radius r is allowed to fall under gravity through a column of viscous liquid of coefficient η . After some time the velocity of the ball attains a constant value known as terminal velocity, V T .The terminal velocity depends on mass of the ball ' m ', coefficient of viscosity ' η ', the radius of the ball ' r ' and acceleration due to gravity g.

Once the measurements for time had become constant over three consecutive distances, terminal velocity had been reached and a ball bearing of a different radius was used. A preliminary experiment was used to determine the maximum radius of ball bearing that would allow the terminal velocity to be reached in the tube and be timed accurately.

The measure of space that an object or material occupies is called as volume. It is commonly measured in gallons, liters, or milliliters. This volume calculator used to calculate the various simple shapes of volume such as cone, cube, ball, cylinder and …

The radius of a sphere is the measure from the center of the sphere to the outer edge. If you are given a problem to calculate volume, you will probably be given the radius. Otherwise, the radius can be difficult to measure because you cannot accurately reach the center of a solid object. [2]

28 Purdue University Physics 152L Measurement Analysis 1 for a measurement decreases, the percentage uncertainty –Z Z £ decreases, and so the measurement deviates less from perfection. For example, a measurement of (2 §1) m has a percentage uncertainty of 50%, or one part in two.

By measuring the diameter of a small precision ball, say 3 mm (0.1181 inch), as it is moved in small increments from the front to the back and then from one side to the other side, an accurate scan of both flatness and parallelism can be made.

The radius of a sphere is the measure from the center of the sphere to the outer edge. If you are given a problem to calculate volume, you will probably be given the radius. Otherwise, the radius can be difficult to measure because you cannot accurately reach the center of a solid object.

In this section, different setups (materials, radii and thicknesses) of sphere balls have been simulated. The metal ball is a double layered sphere (i.e. it is a hollow sphere: the inner sphere is made of air/ the shell is made of metal), the value of thickness of metal ball is the difference between the inner radius and the out radius.

A Ball Plug Gage will absolutely measure the true cylindrical diameter of any hole. If a ball of a well known diameter will pass through an internal cylindrical diameter, we can be absolutely sure that this internal cylinder is at least as large as that ball is in diameter.

A small steel ball of radius 1, placed atop a much larger sphere of radius R, begins to roll under the influence of gravity. Rolling resistance and air resistance are negligible. As the speed of the ball increases, it leaves the surface of the sphere and becomes a projectile. Determine the location at which the ball loses contact with the sphere.
