hai hai Halo Halo sobat semua Mister klik mau  cerita nih tadi Mr klik pergi ke tempat cucian  

mobil Jika kamu perhatikan ada sebuah alat yang  mengangkat sebuah mobil dengan sangat mudah hanya  

dengan membuka keran apa Keren itu berisi air atau  malah berisi udara perlu kalian ketahui alat ini  

dinamakan dengan pompa hidrolik pompa hidrolik  mampu mengangkat mobil yang sangat berat Mengapa  

demikian Tahukah kamu Bagaimana prinsip kerja  alat tersebut sehingga mampu mengangkat mobil  

yang sangat berat nah sebelum membahas lebih  lanjut kita akan belajar tentang prinsip dasar  

tekanan terlebih dahulu simak video berikut ini  jangan lupa subscribe channel Mister klik agar  

rekan-rekan mendapatkan update video pembelajaran  tutorial dan sekilas tentang perkembangan dunia  

pendidikan let's go secara sederhana fenomena  tekanan juga dapat kamu amati pada bebek dan ayam  

Coba kita perhatikan tempat hidup bebek dan ayam  bebek dapat dengan mudah mencari makan di tempat  

yang berlumpur misalnya di sawah sedangkan  ayam kesulitan untuk mencari makan di tempat  

tersebut Mengapa bebek dapat memiliki kemampuan  seperti itu ya di sini kita perlu memperhatikan  

struktur dari kaki bebek dan ayam bebek memiliki  selaput pada kakinya sedangkan ayam tidak memiliki  

rancangan struktur kaki bebek dilengkapi dengan  selaput sehingga bebek dapat mencari makanan di  

tempat yang berlumpur permukaan pijakan yang  luas menyebabkan tekanan yang dihasilkan oleh  

kaki bebek terhadap lumpur itu semakin kecil  sehingga bebek tidak mudah terperosok masuk ke  

dalam lumpur Bagaimana sahabat tentunya Masih  Banyak fenomena di alam yang terkait dengan  

set tekanan sangat menarik untuk dipelajari ya  tentunya kita akan bahas secara satu-persatu dan  

secara sistematis yang pertama kita akan bahas  dulu tentang zat padat Mister klik memiliki  

sebuah pulpen Mister mau tahu bagaimana kalian  merasakan Pulpen ini bukan dijilat atau dibawa  

oleh ya tapi apa yang terjadi apabila Mister klik  tekan ke tangan kalian sebenar kalian pilih ujung  

pulpen atau Pangkal bolpen pilih pangkal Kenapa  nggak sakit berarti kalau yang ujung sakit dong  

rasa sakit itu biasanya enggak Terlupakan doyat  Begitu juga dengan rasa sakit ini jangan dilupakan  

dipakai Pulpen ini rasa yang kalian rasakan  dengan tekanan menggunakan pulpen itu merupakan  

konsep sederhana yang menjelaskan sebuah tekanan  sakit ini menunjukkan tekanan besarnya tekanan  

yang dihasilkan pulpen pada tangan tergantung  pada besarnya dorongan Hai yang biasa disebut  

dengan gaya yang kamu berikan kepada tangan tadi  Tekan ya dan luas bidang tekannya apabila gaya  

yang diberikan pada suatu benda semakin besar  maka tekanan yang dihasilkan juga akan semakin  

besar dan apabila luasan permukaan benda semakin  kecil tentu tekanan yang dihasilkan semakin besar  

seperti tadi yang ditekan menggunakan pulpen  jadi tentu akan lebih sakit ketika ditekan  

di ujung yang runcing nah secara matematis perlu  kalian ketahui bahwa tekanan itu dapat dirumuskan  

dengan p = f bagi au2 ya p = f bagian dengan P itu  adalah tekanan dengan satuannya itu adalah Newton  

per meter tapi kadang juga dituliskan dengan pea  itu singkatan dari Pa F itu merupakan gaya dengan  

satuan n a merupakan luas bidang dengan satuannya  M2 setelah mengetahui bahwa besar tekanan  

dipengaruhi oleh gaya dan luas bidang sekarang  kamu pasti sudah paham alasan kenapa bebek lebih  

mudah mencari di tempat Berniaga dibandingkan  dengan ayam Nah itu banyak sekali fenomena yang  

bisa kalian Ahmad ini yang berhubungan dengan  tekanan lanjut setelah tekanan zat padat kita  

akan belajar tentang tekanan zat cair pertama-tama  kita akan berkenalan dulu dengan istilah Tekanan  

hidrostatis sebenar sabar mrp2 punya sebuah  cerita di Indonesia tentunya kalau kita lihat  

itu memiliki lautan yang sangat luas Tuhan telah  menganugrahkan pesona bawah laut Indonesia yang  

sangat indah sehingga kita patut mensyukuri dan  menjaganya namun ada cerita tragis dibalik semua  

itu ada kisah seorang penyelam tradisional atau  yang sering disebut juga dengan penyelam kompresor  

biasanya rombongan penyelam kompresor itu ada lima  orang ada dua penyelam satu nahkoda dan 2 of short  

mesin kompresor mereka berlayar dengan harapan  mendapatkan banyak tangkapan mesin kompresor yang  

biasa digunakan di bengkel itu digunakan sebagai  sumber udara untuk bernafas lebih lihat mesin itu  

akan terhubung dengan selang sepanjang 60 m dan di  ujung selang itu dipasang dakor yang digigit oleh  

penyelam ya untuk mendapatkan udara untuk bernafas  faktor ketidaktahuan akan metode menyelam yang  

benar dan aman serta anggapan bahwa hal itu sudah  menjadi hal yang biasa sejak zaman nenek moyang  

bisa menjadi musibah sahabat berbagai gejala  pun dialami biasanya ada sesak nafas batuk nyeri  

kepala vertigo nyeri telinga bahkan ada kelumpuhan  loh akibat menyelam yang terlalu dalam nah coba  

kita perhatikan Hai kalau misalnya terlalu dalam  untuk Pasti sangat mungkin melayani jadi kalau  

kita cermati secara sederhana jika nelayan itu  menyelam terlalu dalam dapat membahayakan telinga  

mereka semakin ke dalam tekanan air semakin tinggi  tekanan tinggi bisa membuat telinga terasa penuh  

dan bila didiamkan dan tekanan semakin tinggi Maka  gendang telinga bisa pecah sangat bahaya sahabat  

kedalaman zat cair dan massa jenis zat cair itu  mempengaruhi tekanan yang dihasilkan oleh zat cair  

yang nantinya disebut dengan tekanan hidrostatis  jadi semakin dalam zat cair semakin besar  

tekanan yang dihasilkan semakin besar massa jenis  semakin besar pula tekanan yang dihasilkan secara  

matematis dapat diformulasikan bahwa tekanan PSI  to = rockalight ekali hp2 tekanan yang satuannya  

n per m2 Hai atau pea roh itu adalah massa jenis  zat cair dan satuannya kg per meter pangkat 3 GB  

itu adalah percepatan gravitasi dengan meter per  sekon pangkat dua dan ha itu adalah kedalaman zat  

cair dengan satuannya m dan perlu kalian ketahui  kedalaman itu selalu diukur dari bawah atau dari  

atas Hai dari atas ini dalam gak yaitu biasanya  ngukurnya adalah dari atas ke bawah bukan dari  

dasarnya tapi dari permukaan airnya itu sangat  penting Sahabat Jadi Tekanan hidrostatis ini  

penting untuk diperhatikan jadi penerapannya  juga biasanya digunakan untuk merancang  

sebuah struktur bangunan dalam penampungan air  misalnya pembangunan bendungan atau pembangkit  

listrik tenaga air para arsitek kapal selam  juga memperhitungkan Tekanan hidrostatis air  

laut sehingga kapal selam mampu menyelam kedasar  laut banyak sekali penerapannya selain fenomenanya  

tentu kalau mengetahui ilmu pengetahuan itu bisa  menerapkan untuk memenuhi kebutuhan sehari-hari  

nah yang ketiga setelah tekanan zat cair tekanan  zat padat kita akan belajar tekanan gas pada  

bagian sebelumnya kamu telah mempelajari bahwa  saat padat dan zat cair ikut memiliki tekanan  

Hai guys juga demikian Pernahkah kalian melihat  balon udara Bagaimana balon udara dapat terbang  

di tunggu sahabat sebelum menuju ke sana  kita bahas dulu bahwa percobaan yang sangat  

sederhana membuktikan tekanan zat gas itu adalah  membalikkan gelas yang berisi air ditutup dengan  

kertas siapa yang mendorong tidak ada bukan  ada lemnya atau yang lain tapi itu menunjukkan  

bahwa gas juga memiliki tekanan ketika gelas  yang berisi air dibalik ternyata kertas dapat  

menahan air di dalam gelas hal ini terjadi  karena kertas mendapatkan tekanan udara dari  

luar yang besarnya lebih besar dari tekanan  air dalam gelas ternyata prinsip tekanan gas  

dimanfaatkan untuk mengembangkan balon udara  balon udara dapat terbang Karena massa jenis  

total dan balon udara itu lebih rendah dari massa  jenis udara disekitarnya sehingga balon udara itu  

bisa terbang dan selenay yaitu bisa diatur atau  mengontrolnya menggunakan temperatur udara yang  

ada di saudara tersebut Nah itu Sahabat Jadi  itu adalah bagaimana konsep tekanan yang ada  

di fenomena-fenomena alam di bumi ini Begitu  juga penerapannya setelah mengetahui tentang  

ilmu tekanan tersebut tentunya ada beberapa  perhitungan nanti di pertemuan selanjutnya  

di video selanjutnya Mister klik akan Jelaskan  bagaimana perhitungan-perhitungan di bab tekanan  

ini ya jadi jangan menjadi tekanan tapi ini buat  latihan kalian mendalami ilmu pengetahuan berikut  

adalah ulasan tentang tekanan zat pada tekanan  zat cair dan zat gas semoga menambah pemahaman  

untuk sahabat semua bagi sahabat semua yang  membutuhkan resume dapat mendownload di kolom  

deskripsi ya jika dan menikmati video-video  mr.big jangan lupa like dan share jangan lupa  

juga subscribe channel Mister klik semoga  video ini bermanfaat Terima kasih ya Hi Ho
