WebOct 14, 2024 · The problem for the motion of bodies in a viscous fluid has numerous applications and has been studied in sufficient detail [1,2,3,4,5,6,7,8].The greatest attention is traditionally paid to the description of the fluid flow near a moving body, where the velocity field depends significantly on the shape and size of the object under study [1,2,3,4,5,6,7,8].
In case of circular motion of a body
Did you know?
WebWhen you exert a force perpendicular to the rod on the mass, the mass exhibits circular motion. In this case, the centripetal force needed comes from the tension exerted on the mass by the rod. A similar situation happens for the roundabout: tensions in different parts of the roundabout act on each other to give the necessary centripetal force.
