Objective 1 to determine the volume and density of ball bearing 2 to determine the volume and density of glass block apparatus vernier caliper, micrometer screw gauge and mechanical balance procedure a) micrometer screw gauge. The falling ball viscometer is well-suited for measuring the viscosity of a fluid, and the method has been stated in international standards 4,5 in the international standards, the method differs from the principle described in refs 1-3 the standards describe an inclined-tube method in which the tube for the falling ball was inclined at 10. Measure and record the mass (m) and diameter (d) of the ball bearings 4 carefully drop a ball bearing into the centre of the liquid and watch it fall as shown in fig 1. Then the density of 6 ball bearings is 678/6 g/cc this assumes that all ball bearings are the same size and made of the same kind of steel note that the factor of 6 cancels out.

For both ball and roller bearings encouraged the formation of specialist bearing manufacturing companies at the turn of the century and thus laid the foundations of. 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. Solutions for chapter 1 problem 41p problem 41p: a steel ball-bearing with a circumference of 325 mm weighs 420 g what is the density of the steel in g/cm3(v of a sphere = circumference of a circle = 2πr. Experiment 1 measurement and density objectives: to measure the mass densities of a few regular-shaped solid objects equipment: this is the only experiment that you need to use a fairly sensitive scale (at least to 1 gram precision) and a metric ruler (usually good to 1 mm precision.

Results: measuring density of ball bearings from the graphs above, it can be shown that the relationship between mass vs volume is linear, so density equals mass divided by volume the relationship between mass vs area and mass vs diameter is exponential. T/ f engineers can measure the diameter of the steel ball bearing to the nearest 0000 01 centimeter this number of decimal places ensures that it is a very accurate measurement. Tests were carried-out on all-steel and hybrid ball bearings from 7206 c series the running parameters corresponded to high-speed, oil-mist lubrication and axially pure light loads conditions.

Experiment 1: measurement chapter 1 introduction 11 introduction in order to learn to properly use a meter ruler, vernier calliper, a stop watch, a travelling microscope and a micrometer screw gauge, we used these instruments to measure the diameter of ball bearing of 3 three different sizes (with diameters of 05cm, 10cm, 15cm), the. Bulk density is defined as the total mass of a body divided by the bulk volume for the purposes of this article, the bulk volume is defined as all space that is interior to the macroscopic envelope surface of the body. Able to calculate the density of the sphere this will be used later â micrometer - the diameter of the ball bearings can be measure accurate to 001mm.

Density of the ceramic ball is 60% lower this leads to a reduction of the centrifugal force and therefore an increase of the maximum rotational speed high hardness and elasticity modules provide less change in the rolling contact resulting in less friction. Density is defined as the average mass per unit volume it is a measure of how much matter is squeezed into a given space the more closely packed the molecules, the higher the density of the material. Ball selection is a low-cost method that involves using preselected, oversized ball bearings to create four points of contact between the nut and screw this permits heavier loads, but friction. Hybrid ball bearings for most ball bearing applications, steel balls are sufficient as applications become more complex and specialized, alternative ball options become a necessity.

To find the density, all you have to do is weigh them and measure the diameter with a micrometer btw there are more than 10,000 unique named metal alloys, so trying to watching up the density with out realizing what your bearings are created from may not be very important. 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. A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluidfor liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used.

Density is a measure of a substance's mass-to-volume ratio for liquids and solids, density is have a tiny steel ball bearing or a large steel beam the mass. The liquid is then placed in a burrette and the terminal velocity of small steel ball bearings is measured by measuring the time required for the ball to drop a given distance - don't forget to measure the diamter of the ball first.

Key factors mass of ball bearing viscosity/density of the fluid surface area of ball bearing texture of the balls surface temperature i am going to investigate how mass affects the terminal velocity. Or you could use water displacement if you know the density of the ball bearing, and use math to calculate the size since a ball bearing is (presumably) a perfect sphere 204 views celle van giel , studied at technical college mechanic (1968. Mass density is defined as the mass per unit volume gm/cm 3 is, therefore, a unit of mass density the mass density ρ of an object may be found by dividing its mass m by its volume v. Bearings are all made of aisi 52100 chromium steel with a known volumetric mass density of 781 grams/cm 3 use your vernier caliper to measure the diameter of each ball bearing and use.
