2 Izibonelo zemibuzo yokulingana komzimba eqinile

I-1. F₁= 10 N, F₂= 15 N kanye no-F₄ = 10 N, isebenza kubhulokhi i-ABCD njengoba kuboniswe esithombeni. Ubude bebhulokhi i-ABCD bungamamitha angu-20. Thola u-F₃ ukuze ibhlokhi libe se-static equilibrium. Unganaki ubunzima bebhlokhi.
Ingxoxo:

2. Amabhokisi A (10 kg) kanye no-B (20 kg) abekwe ebhodini lokhuni. Ubude bebhodi = amamitha ayi-10. Uma ibhokisi B libekwe amamitha ama-2 ukusuka ku-fulcrum, kufanele ibhokisi A libekwe ibanga elingakanani ukusuka ku-fulcrum ukuze ibhodi lingajikelezi? (g = 10 m/s²)

Ingxoxo:

Isinyathelo 1: dweba umdwebo wamandla asebenza entweni

Isinyathelo 2: ukuxazulula inkinga

Bheka umdwebo ongenhla. Amandla asebenza ebhodini amandla adonsela phansi ebhokisi B (w)_B), isisindo sebhokisi A (w_A), amandla adonsela phansi ebhodini (ibhodi le-w) kanye namandla avamile (N). Iphuzu le-pivot liyi-axis yokujikeleza. Isisindo sebhodi (ibhodi le-w) kanye namandla avamile (N) kuvumelana ne-fulcrum/axis yokujikeleza ukuze ingalo yamandla ibe yi-zero. ibhodi le-w kanye ne-N azifakiwe ekubalweni.

FUNDA FUTHI Izibonelo zemibuzo yomfutho kanye neyokushukuma

I-Torque 1 = i-torque ekhiqizwa amandla adonsela phansi ebhokisi B (i-torque enhle)

I-torque 2 = i-torque ekhiqizwa amandla adonsela phansi ebhokisi A (i-torque engemihle)

Ibhodi lisesilinganisweni esingaguquki uma i-torque iyonke = 0.

Ukuze ibhodi lilinganiswe ngokulinganayo, into A kumele ibekwe amamitha angu-4 ukusuka endaweni yokusekela.
