Abstract
Ovim radom opisane su osnovne podjele sila u Hidromehanici, njihov nastanak i klasifikacija. Za opis sila uz teoretske opise korišteni su matematički modeli i različiti primjeri. Opisana su djelovanja masenih sila na tijela različitih volumena i uveden je pojam jediničnog vektora masene sile za opis sile preko volumenskog integrala. Djelovanja površinskih sila na različite ravninske i zakrivljene površine opisana su preko površinskog integrala pomoću vektora naprezanja, te je opisana uloga sila uzgona i trenja u površinskim silama. Razmatrana su naprezanja izazvana masenim i površinskim silama i predstavljen je tenzor naprezanja kao način opisivanja naprezanja u fluidu. Objašnjena je uloga tih sila i naprezanja u ravnoteži sila u fluidima, dana je formulacija za ravnotežu sila i uveden je pojam divergencije naprezanja za opis površinskih sila u toj jednadžbi. Predstavljen je laboratorijski model kojim se eksperimentalno dolazi do iznosa hidrostatske odnosno površinske sile.
Abstract (english)
This paper describes the basic divisions of forces in Fluid mechanics, their origin and classification. Mathematical models and various examples were used to describe the forces in addition to the theoretical descriptions. The effects of body forces on bodies of different volumes are described and the term unit vector of body force is introduced to describe the force over the volume integral. The effects of surface forces on different planar and curved surfaces are described over the surface integral by means of a stress vector and the role of lift and drag forces in surface forces are described. Stresses caused by body and surface forces are considered and the stress tensor is presented as a way of describing stresses in a fluid. The role of these forces and stresses in the balance of forces in fluids is explained, a formulation for the balance of forces is given, and the notion of stress divergence is introduced to describe surface forces in that equation. A laboratory model is presented which experimetally arrives at the magnitude of hydrostatic or surface force.
