SLED Design Project Simple Machines The Lever Your skeletal muscles work as levers to move your body The Lever The Wheel and Axle http videosiftcom videoNatureinventedthewheel Salamanders and Caterpillars oh my. 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.. By:. Drew Harris. Simple machines. The basic machines that make up other machines are called . simple machines. . There are six of them. They are lever, pulley, wheel and axle, inclined plane, screw, and wedge. All these machines help us move things by changing the size of the force applied, the direction of the force, or both at once. . Simple Machines. A simple machine has few or no moving parts.. Simple machines make work easier.. With or without a simple machine the work is the same.. Also when simple machines are combined they can make complicated bigger machines.. Nature of Machines. Machines are any device that transfer a . force . from one . place. to . another. .. Nutcracker, ramp, engine. All . complicated. machines contain many small . simple. machines.. 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?. A simple machine is any of the basic mechanical devices for applying a force, such as an inclined plane, wedge, or lever.. Simple machines are utilized to reduce the amount of force required to perform work, initiate or resist motion, break or split molecular bonds of solids, or keep two non-molecularly-bonded solid objects bound together.. 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. . 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. Pay attention. Simple Machines. Simple machines assist us in doing work by creating a mechanical advantage.. They . do not . change the amount of work; they lower the effort force. There are 6 types of simple machines: lever, inclined plane, pulley, wedge, screw, and wheel and axle.. 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). . 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. Rube Goldbe
