3-LАBОRАTОRIYA ISHI
Xalqani tebratish metodi bilan og’irlik kuchi tezlanishini aniqlash
Lаbоrаtоriya ishini bаjаrish sаnаsi: ______________________
Ishning maqsadi:
Turli xil radiyuslihalqachalarning tebratish metodibilan og’irlik
kuchi tezlanishini aniqlashdan iborat.
Kerakli asboblar
: Gorizontal o’qqa osilgan xalqa, shtangensirkul’
yoki lineyka, sekundomer.
Ishni bajarish tartibi
1.
Sirkul’ yoki lineyka bilan xalqaning ichki R1 va tashqi R2 radiuslari topiladi.
2.
n ta tebranish uchun ketgan vaqt
aniqlanib, tebranish davri topiladi.
3.
Xalqaning radiusi va tebranish davri hisoblanib o’rtachalari olinadi.
4.
Tajriba 3 marta o’tkazilib 1 – jadvalga yoziladi.
5.
Absolyut va nisbiy xatolar topiladi.
