PPT-What are simple machines and how are they useful?

Physical Systems Simple Machines Simple Machines A simple machine is a device composed of only one or two parts that requires a single force to work The stapler works by applying a single downward force at its open end . What is a Simple Machine?. A simple machine has few or no moving parts.. Simple machines make work easier. Wheels and Axles. The wheel and axle are a simple machine. The axle is a rod that goes through the wheel which allows the wheel to turn. November 24. th. -25. th. . Goal:. I will be able to explain the relationship between mass, force and distance traveled. . I will be able to describe the difference between different simple machines. . Tried to take a super heavy object up a flight of stairs ? WHAT HAPPENED. Example. Have you ever . Tried to cut a cake with out a knife?. Example. Have you ever . tried to unscrew a nut, bolt, or screw from something with your bare hands and discovered that it was just too tight to loosen even if you had a good grip? . Inclined Plane, Wedge, Screw, Lever, Wheel & Axle, Pulley.. By: . Shae. Anderson. What is a simple machine?. A simple device for altering the magnitude or direction of a force. . A simple machine has few or no moving parts.. A. 5. th. Grade Smarty Pants?. Simple Machines Song. A bar that turns against . an unmoving point is called a…. Wheel and Axel. Lever. Pulley. Wedge. Video. A bar that has an inclined plane wrapped around it is called a…. Pulleys. The Big Idea of this Investigation. A simple machine is a mechanical device that makes work easier by magnifying, modifying, transferring, or changing the direction of applied force. Simple machines are the elementary "building blocks" of which all complicated machines are made.. If we did not have the large machines that we have today for building, would we still be able to make these large structures? Why?. 2. Essential Question:. How do simple machines make life easier for us?. including Finite State Machines.. Finite State MACHINES. Also known as Finite State Automata. Also known as FSM, or State . Machines. Facts about FSM, in general terms. Finite State Machines are important . Why do we use machines?. Machines make doing work easier.. But they do not decrease the work that you do.. Instead, they . change the way you do work.. In general you trade more force for less distance or less force for more distance. IPC Spring . 2014. Energy, Work, Power & Machines. 1. Energy. is the ability to do work. .  . Potential energy. – stored energy or energy due to position.  . PE=m g h . m. is mass (kg). g. 2. SIMPLE MACHINES - LEVER. A lever is a rigid bar that rotates around a fixed point called the fulcrum.. The bar may be either straight or curved.. In use, a lever has both an effort (or applied) force and a load (resistant force). . What is a machine?. A machine is simply a device that makes doing work easier. . Even a sloping surface can be a machine. . Using Machines. Mechanical Advantage. Even though machines make work easier, they don’t decrease the amount of work you need to do. . Have you ever played that zany game called Mouse Trap? That series of events produced by a bunch of simple machines brought together to achieve one task, is called a Rube Goldberg Machine.
