Materi Pembelajaran
Archimedes Principle
Hukum Archimedes
Archimedes Principle , which states that “ when a objects is immersed in a fluid
,the apparent loss of weight of an objects is equals to the upthrust and this is also equal
to the weight of the displace fluid “. Hukum Archimedes menyatakan bahwa “ bila
sebuah benda dimasukan dalam zat cair, besar gaya apung benda sama dengan gaya
angkat yang besarnya sama dengan berat benda yang dipindahkan ke zat cair “.
Archimedes principle is mathemathically formulated as ( secara matematis , hukum
archimedes dirumuskan ) :
Where FA is bouyant force , ρf is densiti of fluid , and Vbf is the volume of
immersed body. Dimana FA adalah gaya apung , ρf adalah massa jenis fluida , and Vbf
adalah volume benda yang tercelup.
There are three possible case of a body in a fluid , i.e floating, barely floating
and sinking. Ada tiga keadaan benda dalam zat cair, yaitu terapung, melayang dan
tenggelam.
1. Floating
Terapung
A object is said to be floating if only some of parts of the objects is
beneath the water surface and the other parts is above the water
surface.Benda dikatakn terapung jika sebagian dari benda berada dibawah
permukaan air dan bagian yang lain berada diatas permukaan air. The
magnitude of bouyant force is equals to the body’s w.Besarnya gaya
Archimedes sama dengan berat benda.
FA = mg
Vf ρf g = Vb ρb g
Vf ρf = Vb ρb
FA = ρf Vbf g
5. 2. Barely Floating
Melayang
On barely floating objects , the magnitude of bouyant force is equal to
the objects weight.Pada benda melayang besarnya gaya Archimedes sama
dengan berat benda.Hence for a barely floating objects we have the relation
Syarat benda dikatakan melayang adalah ρf = ρb .
FA = w
Vf ρf g = Vb ρb g
ρf = ρb
3. Sinking
Tenggelam
When an object is sinking its means that the bouyant force acts on the
object is smaller than its weight. Pada saat benda tenggelam besar gaya
Archimedes lebih kecil dari berat benda. The volume of the immersed
objects equals to the total volume of the objects. Volume benda yang
tercelup sama dengan volume benda. An Object sinks in a fluid when
density is greather than the density of the fluid.benda akan tenggelam dalam
zat cair jika massa jenis benda lebih besar dari massa jenis fluida.
FA > w
Vb ρb g > Vf ρf g
ρb > ρf
6. Archimedes Principle is widely used in either technology or
science. Prinsip archimedes banyak diterapkan baik dalam tekologi
atau sains. Some example of device that work based on it (beberapa
contoh alat yang menggunakan prinsip itu :
