Simple Machine Project - University of Hawaii.
Humans use simple machines every day, possibly without even noticing. A car, for example, uses its axles and wheels to make moving easier by redistributing the force caused by its bulk onto more mobile surfaces, and parts of a car are held together by screws or tightened or loosened by a wrench, an applied use of leverage. In short, simple machines change the way force is applied to an object.
These six machines form the basis for many more complicated creations that help to make life easier. Many students are required to create simple machines for science projects. Building a whirligig in a shoebox combines the lifting power of a lever with the turning motion of a wheel and axle to create a fun and simple project.
A wedge is a simple machine that almost looks like a ramp or an inclined plane. It is actually made up of two inclined planes joined together. It can be made of wood, metal, stone, or plastic. It is thick on one end and usually thins out to a sharp edge on the other end. They come in all sizes and usually have handles attached to them. Examples of Wedge: Wedges can be used in many different.
The basic purpose for which most simple machines are designed is to reduce the effort (force) required to perform a simple task. To achieve this, the force applied must act over a longer distance or period of time resulting in the same amount of work being performed by a smaller force. Screws, levers and inclined planes are designed to increase the distance over which the reduced force acts so.
Learning about the six simple machines has never been more fun! Through exciting science projects and activities kids can easily do at home or school, tomorrow’s scientists and engineers will have a blast learning about simple machines and how they make daily life easier. This book is the perfect STEM companion for curious minds at home or in the classroom.
The kinds of devices that are characterized by simple working mechanisms, which make it easier for us to accomplish various tasks, are called simple machines. The direction as well as the magnitude of applied forces can be changed with the help of such devices. Thus, the force applied is used to move, lift, and even fix an object or a load, in the form of work. A few of our body parts also.
