How would you determine density of a ball bearing?
The mass density ρ of an object may be found by dividing its mass M by its volume V. Sphere: V = (4/3) π R3 where R is the radius of the sphere. Cylinder: V = π R2L where R is the radius of its base and L the length of it.
What is the density of the ball?
The radius of 1.5 inches cubed equals 3.375 ⋅ 4 ⋅ π = 42.410 , divided by 3, equals 14.137 cubic inches, times 0.409 ( the density of lead ) gives 5.782 pounds….What would a three inch diameter lead ball weigh?
| Material | Density ( grams / cm³) |
|---|---|
| Steel | 7.86 |
| Titanium | 4.51 |
| Water ( liquid ) | 1.00 |
| Zinc | 7.14 |
What is the formula for finding mass?
To find an object’s mass using its weight, the formula is Mass equals Weight divided by the Acceleration of Gravity (M = W ÷ G).
What are two ways to calculate density?
The most accurate way to calculate the density of any solid, liquid or gas is to divide its mass in kilograms by its volume (length × width × height) in cubic metres. The unit for density is kg/m 3. The density of water is approximately 1000 kg/m 3 and the density of air is approximately 1.2 kg/m 3.
What units are used for density?
Density has the units of mass divided by volume such as grams per centimeters cube (g/cm3) or kilograms per liter (kg/l).
How do you type Ø?
Ø = Hold down the Control and Shift keys and type a / (slash), release the keys, hold down the Shift key and type an O.
What is Ø in English?
Ø (or minuscule: ø) is a vowel and a letter used in the Danish, Norwegian, Faroese, and Southern Sami languages. Though not its native name, among English-speaking typographers the symbol may be called a “slashed O” or “o with stroke”.
How do I type a Ø in Word?
To easily insert the diameter symbol (Ø) on Word: using the keyboard, press Ctrl+/, then press Shift+O. This should give you the diameter symbol or O with slash through it. Alternatively, press down the Alt key, then press the symbol’s Alt code – 0216.
Is Ö the same as Ø?
In many languages, the letter “ö”, or the “o” modified with an umlaut, is used to denote the non-close front rounded vowels [ø] or [œ]. In languages without such vowels, the character is known as an “o with diaeresis” and denotes a syllable break, wherein its pronunciation remains an unmodified [o].
How is ø pronounced in English?
Æ is pronounced like the “a” in the word sad, Ø sounds like the “u” in the word burn, and Å sounds like the “o” in born. Proper pronunciation is one of the keys to speaking the language correctly so people can understand you.
What is æ called?
Today, the International Phonetic Alphabet uses it to represent the “a” sound in the English word “cat”. ) which it transliterated; its traditional name in English is still ash (/æʃ/).
