  • What are the Effects of Earthquake on Structures

    The generation of inertia forces in a structure is one of the seismic influences that detrimentally affect the structure. When an earthquake causes ground shaking the base of the building would move but the roof would be at rest. However since the walls and columns are attached to it the roof is dragged with the base of the building. Forces prediction during material deformation in abrasive To study the finishing mechanism of abrasive flow machining (AFM) theoretical model of forces acting on a single grain has been developed. An experimental research has been carried out by measuring the axial force radial force and active grain density during the AFM process.

  • Motion on a CurveEastern Illinois University

    Motion on a Curve => The net force on a car traveling around a curve is the centripetal force F c = m v 2 / r directed toward the center of the curve. => For a level curve the centripetal force will be supplied by the friction force between the tires and roadway. => A banked curve can supply the centripetal force by the normal force and the weight without relying on friction.
