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

1.63. G`ildirak shunday aylanadiki, g`ildirak ra­diusining burilish burchagi bilan vaqt orasidagi bog`lanish = A Vt + St+Dt<sup>3</sup> tenglama orqali beriladi, bunda V = 1 rad/s, S = 1 rad/s<sup>2</sup> va D = 1 rad/s<sup>3</sup>, xarakatning ikkinchi sekundining oxirida g`ildirak gardishidagi nuqtalarning normal tezlanishi a =3,4610² m/s² ga teng bo`lsa, g`ildirakning R radiusi to­pilsin.

1.64. Aylanayotgan g`ildirak gardishidan nuqtalar to`la tezlanishining vektori shu nuqtalar chiziqli tezligining vektori bilan 30° burchak tashkil qilgan paytdagi nuqta a normal tezlanishining a tangentsial tezlanishidan necha marta kattaligi topilsin.
