The moge ike
1. Ike atọ na-arụ ọrụ n'elu osisi nwere ogologo mita isii, dịka egosiri na foto dị n'okpuru. Gịnị bụ ike net na-agbagharị ogwe ahụ gburugburu isi ihe O dị ka axis nke ntụgharị?
A maara:
Axis nke ntụgharị na isi O.
Ike 1 (F)1) = F
Anya dị n'etiti ahịrị ọrụ nke F1 na axis nke ntụgharị (r)1) = mita atọ
Mmiri ndị dị n'usoro na ndị yiri ya - nsogbu na ngwọta
1. Ihe dị gram 160 na-arapara n'otu nsọtụ nke isi iyi, mgbanwe n'ogologo isi iyi ahụ bụ sentimita 4. Gịnị bụ mgbanwe n'ogologo atọ ahụ? isi iyi ejikọtara na usoro na parallel, dịka egosiri na foto dị n'okpuru?
A maara:
Mgbanwe n'ogologo nke mmiri (Δx) = 4 cm = 0.04 m
Mass (m) = gram 160 = 0.16 kg
Ọsọ ọsọ n'ihi ike ndọda (g) = 10 m/s2
Mgbanwe nke mmegharị ntụgharị - nsogbu na ngwọta
1. Pulley nwere oge nke inertia I = 2/5 MR2 nwere ibu nke kilogram abụọ. Ọ bụrụ na ọ dị oge ike na pulley bụ 4 Nm, kedu ka o si bụrụ osooso nke pulley. Ọsọ ọsọ nke ike ndọda bụ g = 10 ms-2.
Mara :
Oge nke inertia nke pulley (I) = 2/5 MR2
Mass nke pulley (M) = 2 kg
Oge ike (τ) = 4 Nm
