4-mashg`ulot. Aylanma harakat dinamikasiga doir masalalar yechish

1.61. Radiusi R = 5 sm bo`lgan g`ildirak shunday ay­lanadiki, g`ildirak radiusining burilish burchagi bilan vaqt orasidagi bog`lanish = A + Vt + St+Dt tenglama orqali beriladi, bunda D = 1 rad/s^g. Harakatning har sekundida g`ildirak gardishida yotgan nuqtalar uchun tan­gentsial tezlanish a ning o`zgarishi topilsin.

1.62. Radiusi R=10 sm bo`lgan g`ildirak shunday aylanadiki, g`ildirak gardishidagi nuqtalar chiziqli tezliginiig vaqtga bog`lanishi v = At + Vt tenglama orqali beriladi, bunda A = 3 sm/s² va V = I sm/s. Harakat boshlangandan t=0, 1, 2, 3, 4 va 5 s o`tgandan keyin to`la tezlanish vektori bilan g`ildirak radiusi orasidagi burchak topilsin.
