1)Introduction A machine tool is a powered mechanical device‚ typically used to fabricate metal components of machines by machining‚ which is the selective removal of metal. Machine tools can be operated manually‚ or under automatic control. Early machines used flywheels to stabilize their motion and had complex systems of gears and levers to control the machine and the piece being worked on. Soon after World War II‚ the numerical control (NC) machine was developed. NC machines used a series

hanicalSimple Machines and its Mechanical Advantage What are Simple Machines? What do we mean by Mechanical Advantage? Simple Machines * creates a greater output force than the input force Therefore since work is performed by applying a force over a distance‚ with the use of these machines we can do more work with lesser effort than working with our bare hands. In short‚ they make work easier. Mechanical Advantage * The Ratio between the input force and the output force. * The measure

Simple machines are extremely important to everyday life. They make stuff that is normally difficult a piece of cake. There are several types of simple machines. The first simple machine is a lever. A lever consists of a fulcrum‚ load‚ and effort force. A fulcrum is the support. The placing of the fulcrum changes the amount of force and distance it will take in order to move an object. The load is the applied force. The effort force is the force applied on the opposite side of the load

In The Machine Stops‚ E.M. Forster projects life years from now where people live underground with extreme technological advances. Also‚ people live separated in little rooms where they find a variety of buttons they can press in order to perform any task they desire. They do not communicate with people face to face as often as we do now. Without a doubt‚ their society is very different from ours. All of the inhabitants are used to living along with the Machine and it is hard for them to imagine
