use on each axle? What is the effect of using large or small wheels? For this project‚ we used water bottle caps wrapped in electrical tape. The size of the wheel in comparison to the axle it is placed on greatly affects the torque (or the pulling force) as well as the pulling distance. If you larger wheels and a smaller axle‚ you will achieve greater distance but less power. Therefore‚ you must find a balanced ratio between the size of the wheel and the axle because if it has too little power‚ it

affects how much centripetal force affects an object. Centripetal force plays a major part in every day life. This force is the reason for the sensation of being ‘pushed’ into the car door that passengers in a car feel when the driver makes a sharp left turn (The Centripetal Force Requirement‚ n.d.). It is the reason people feel almost weightless on rollercoasters‚ and on an even larger scale‚ it is what keeps the moon orbiting around Earth. Without centripetal force‚ cars would not be able to make

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
