Vector Mechanics Activity #1 N2 Name: Angel Leonardo Santos Cruz ID:1942628 Mechanics and its branch’s Mechanic is a science concerned with the motion of bodies under the actions or forces, including the case in which the body remains at rest Mechanics may be divided into three branches: Statics which deals whit forces acting on and in a body at rest, kinematics, which describes the possible motions of a body or system of bodies; and kinetics, which attempts to explain or predict the motion that will occur in a given situation. Alternatively, mechanics may be divided according to the kind of system studied. The simplest mechanical system is the particle, defined as a body so small that its shape and internal structure are of no consequence in the given problem. Why is important study statics? It’s important because have proved especially useful in designing buildings, bridges, and dams, as well as cranes and other similar mechanical devices. To be able to calculate the dimensions of such structures and machines, architects and engineers must first determine the forces that act on their interconnected parts. Statics provides the analytical and graphical procedures needed to identify and describe these unknown forces. Transmissibility principle/Equivalent force The principle of transmissibility states that the point of application of a force can be moved anywhere along its line of action without changing the external reaction forces on a rigid body. Any force that has the same magnitude and direction, and which has a point of application somewhere along the same line of action will cause the same acceleration and will result in the same moment. Therefore, the points of application of forces may be moved along the line of action to simplify the analysis of rigid bodies. Explain the transmissibility principle or equivalent force with 6 or more examples A box being pushed or pulled in the same direction The power needed in the direction of the cd driver The resistance applied in a car. the force applied to a nail on a board the force applied to a rope being pulled by a from a wall the force resulting from two forces at the ends of a rigid body in opposite directions All the examples have a force applied in one direction, that means that you can move the force in all the same direction to simplified the problem. Define clearly line of action of a force Line of action is the axis along which the force is applied. Unlike the force vector which begins at the point where the force is applied and extends according to the magnitude of the force, the line of force goes through the point and extends indefinitely in both directions. How long is the length of a line of action of a force?
