    Mechanical Engineering Notes – On Inertia Force Analysis – For W.B.C.S. Examination.

    A dual dynamic equation, based on dual vectors and screw calculus, is formulated here to provide a concise analytical tool for the study of the dynamics of rigid members in any complex mechanical system. In this paper the equation is applied to inertia force analysis of an RCCC mechanism of general proportions; bearing reactions and inertia torque are obtained in closed form dual-number expressions. Such analytical expressions are more susceptible for geometric interpretation and well adapted for digital computation.Continue Reading Mechanical Engineering Notes – On Inertia Force Analysis – For W.B.C.S.

    The main component required for constructing the
    engine including the ship reciprocating engine are piston,
    connecting rod, crankshaft, cylinder, and engine block.
    During the operation of ship reciprocating engine, the
    piston moves translatively and the crankshaft moves
    rotatively; furthermore, the connecting rod that has
    function to connect piston and crankshaft, more variably,
    translatively or rotatively.
    Therefore, the magnitude of dynamic inertia force
    cannot be measured since the components are inside the
    engine and they move rotatively; as a result a numerical
    approach is needed. For these reasons, some researchers
    developed physical and mathematical models of the
    dynamic inertia forces of some engine components.
    Astashev et. al.. created mathematical modeling for the
    construction of two stroke engine. It is stated that the
    total of inertia moment of engine components is
    equivalent to the amount of each component of the
    mechanism of engine moment.

    nertial force, also called Fictitious Force, any force invoked by an observer to maintain the validity of Isaac Newton’s second law of motion in a reference frame that is rotating or otherwise accelerating at a constant rate. For specific inertial forces, see centrifugal force; Coriolis force; d’Alembert’s principle.

    Inertia is a property of matter. According to Newton’s Law of Inertia, an object at rest tends to stay at rest unless acted upon by a force. Likewise, an object in motion tends to remain at that velocity unless acted upon by some force.

    The concept of an inertial force comes from Newton’s Laws of Motion, which can be stated as:

    That equal and opposite reaction is called the inertial force. It is a factious or pseudo force equal to −F = ma.

    What that means is that there is no such thing as a unidirectional force or a force that acts on only one object. There must always be two objects involved, acting on each other. One object acts on the other, while the second resists the action of the first.

    When you apply a force on a freely moving object in order to accelerate, decelerate, or change its direction, an equal inertial force acts on the object in an opposite direction of your applied force.

    You can experience or feel that inertial force. If there were no inertial force, the object would just move when you pushed on it.

    When an applied force acts on you, you can feel the inertial force opposing the applied force. However, it is not as obvious as when a force is applied on you.
