basketball has some type of force working upon it. For example‚ without friction a basketball player would be unable to stop because inertia states that objects in motion tend to stay in motion. Without friction acting upon the player‚ there is no force to stop him‚ until he hits a wall that is. With this information you can come to the conclusion that without forces‚ there would be no game of basketball. However‚ what exactly is a force? Webster’s dictionary defines force as a push or pull that can

load (vertical). It resists the applied loading by a combination of internal transverse shear force and bending moment. An accurate analysis required in order to make sure the beam is construct without any excessive loads which affect its strength. A bending moment exists in a structural element when a moment is applied to the element so that the element bends. Moments and torques are measured as a force multiplied by a distance so they have as unit newton-metres (N·m). The concept of bending moment

if a force with the same magnitude at opposite angles would equal to a net force of zero. If we equalize all the forces so we get a net gain force of 0 then no weight should touch the floor or the pulleys. We then tested if we added an extra weight with certain angle. We found out at what angle and what weight would equalize the force. The dependent variable is the force we used to equalize the force table. The controlled variables are the weight we initialized to create an unbalanced force. Equipment

work on the principles of gravity and air resistance and in effect‚ terminal velocity. Air resistance (air friction) Air resistance is an upward force exerted on a body while it is in the air and is the result of air molecules that come in contact with the surface of the falling object. This force attempts to counteract gravity and other downwards forces influencing a body. The amount of air resistance encountered by an object is dependent on two factors: speed of the object and surface area. Air

The Five Competitive Forces Model In this section‚ the structure of our company will be explained using the five competitive forces model developed by Harvard professor Michael Porter. These forces include: rivalry among existing firms‚ threat of new entrants‚ bargaining power of buyers‚ threat of substitutes and bargaining power of suppliers. Each of these forces will have their own distinctive effect on determining industry profitability. Intensity of rivalry among competitors: Recently there

systems all forces and torques sum to zero. In problems where the first and second conditions of equilibrium are satisfied‚ the best strategy is to create FBD’s for both the first and second conditions‚ derive equations based on these FBD’s and then see what useful information may be gleaned from these equations. When applying the second condition we are free to choose any axis about which to compute torques. It is best to choose an axis that eliminates one or more forces that have lines of force that pass

Six Forces Porter’s forces analysis is a framework for industry analysis and business strategy development that draws upon industrial organization economics to determine the competitive intensity and overall industry profitability. These forces are 1) potential entry of new competitors‚ 2) bargaining power of suppliers‚ 3) bargaining power of buyers‚ 4) substitute products‚ 5) rivalry among competing sellers in an industry‚ and 6) power of stakeholders. A change in any of the forces normally

Addition of Force Vectors Abstract The purpose‚ of this experiment‚ was to prove that there is a relation between the magnitude of the resulting vector‚ and the angle between the vectors that are being added. The test was performed by creating a balance between three weights tied to strings on a pulley that transferred the string on top of a graduated disc‚ which made easy the measurement of the angles between them. After performing the experiment‚ my group concluded that there is a relation
