Composition of Concurrent Forces Abstract— The experiment aims to show the relationship of different forces acting at the same time by using different variables namely‚ the equilibrant force‚ the resultant‚ and the given forces Fa and Fb. The equilibrant force is the force that establishes equilibrium while the resultant is the addition of the given forces and is also the opposite of the equilibrant. The objective of the experiment is to determine the resultant of two forces experimentally‚ to be

and in most cases are assumed to be equally or uniformly distributed. a- Uniformly distributed load. a- Uniformly varying load. Concept of Shear Force and Bending moment in beams: When the beam is loaded in some arbitrarily manner‚ the internal forces and moments are developed and the terms shear force and bending moments come into pictures which are helpful to analyze the beams further. Let us define these terms Now let us consider the beam as shown in fig 1(a)

is the tendency for a body to either remain at rest or move in a straight line at a constant speed‚ unless acted up by an unbalanced force. In both cases‚ the item has an acceleration of zero. Inertia is not a force‚ but rather a resistance to a change in velocity. In other words‚ the object wants to stay put or stay constant‚ and inertia is what happens when a force gives it acceleration. An example of inertia in the physical world happens while riding in a car. The driver turns the car left‚ but

1. Porter have developed five forces‚ basically it is a framework to analyze the level of competition within an industry in order to develop a business strategy. The first force as what Porter defined is the threat of new entrants‚ which can eventually decrease the profitability for all firms in their particular industries. This happens whenever profitable markets yield high returns that can attract new firms. The second force is the threat of substitute products or services or products‚ this is

Force 4: Buyer Power Buyer power is one of the two horizontal forces that influence the appropriation of the value created by an industry (refer to the diagram). The most important determinants of buyer power are the size and the concentration of customers. Other factors are the extent to which the buyers are informed and the concentration or differentiation of the competitors. Kippenberger (1998) states that it is often useful to distinguish potential buyer power from the buyer’s willingness

us believe that theirs is the biggest and best‚ the one we’ve been missing. Beyond the radio ads and TV commercials are the main competitive forces behind that competition and that is what I would like discuss in the next few paragraphs. Before I go specifically into the world of Sony electronics‚ I am first going to define in general the 5 competitive forces in industry. At the center of it all are the Industry Competitors. Next‚ there is the Threat of New Entry‚ which puts pressure on prices‚ cost

Forces Have you ever wondered how forces link to our life? Everything we’ve learned in science has got me thinking about it. Forces are an essential part of our daily lives. Forces act on all objects. And we need force for everything we do‚ whether it’s a push‚ pull or twist. Force gives an object the energy to move‚ stop moving or change direction. Newton’s first law states that an objects velocity cannot change unless it is acted upon by a force. Here are examples of force in everyday life.

equilibrium of forces was investigated through the use of different weights attached to cords which were connected to a central ring‚ while pulleys supported them. This assembly facilitated the force band system to demonstrate that equilibrium will be attaining regardless of disturbances. However‚ due to errors in the experiment‚ the sum of the x and y component did equate to zero as predicted. The graphical solution of the experiment yield a polygon that is completed indicating that all the forces are in

When you hear the word aerodynamics‚ the first thing that comes to mind is airplanes and pilots. There are other applications that apply. For instance‚ the passing of a football. A football that is thrown into the air has inertia. This is the tendency of an object in motion to remain in motion. But because of gravity the ball is pulled down and resistance that slows the ball down. A quarterback through the motions of his and body‚ must balance the forward momentum that he gives the ball‚ fighting
